'Love Is Blind''s Chelsea & Megan Fox
This one was a bit more controversial, but the Love Is Blind contestant shared with her still-unseen fiancé that she had received comparisons to the Jennifer's Body actress in the past as they shared information about each other from behind an opaque screen.
When viewers weighed in (often unkindly) on the resemblance, Chelsea went on social media to amplify a message from her friend instructing people to "cool it."

Emma Mackey & Margot Robbie
In an interview withBuzzfeed, Robbie explained thatEmma Mackey— who plays theNobel Prize-winning physicist Barbie— was cast for a very specific reason: people think she and Robbie look alike.
“She plays one of the Barbies in the movie pretty much because Greta and I thought it would be funny. We were gonna do this whole joke about us looking similar,” Robbie said in a joint interview with Gosling.
But, Robbie said, once they had their hair color set for the movie (Emma as a dark brunette, Margot in stereotypical Barbie blonde), the resemblance was less noticeable, so the joke was scrapped.

Keira Knightley & Natalie Portman
These two brunette stars look so alike that the Star Wars: The Phantom Menace producers couldn't help but take notice — and cast Knightley as the body double for Portman's Queen Amidala in that film. The two are mistaken for each other so often that Knightley says people have chased her down in airports, thinking she's the Black Swan star. "I feel quite sorry for her because she must get chased a lot because it's happened like five times where someone's been like, Natalie! Natalie! Natalie!' And I'll sign and take a picture as Natalie," Knightley joked.
In a 2024 interview with Vanity Fair, Portman said she's still mistaken for Knightley "all the time" — and finds it "very flattering."

Reese Witherspoon & Carrie Underwood
They're blonde, Southern and multitalented, so it's no wonder that they've occasionally been confused for one another. Luckily, they both take it as the huge compliment it is.
"To the woman in the parking lot who just asked me if I wasCarrie Underwood: You officially made my day!" Witherspoon Tweeted in 2020.
Responded Underwood, "YOUR day?!?!?!?! That lady just made my whole life!"

Brie Larson & Phoebe Bridgers
The Captain Marvel star and the indie-rock star haven't commented on the internet's obsession with their similar appearances, but they have crossed digital paths in at least one way: Brie has paid tribute to the singer by covering her collaboration with Taylor Swift, "Nothing New."

Halsey & Millie Bobby Brown
During an appearance on The Tonight Show Starring Jimmy Fallon in June 2022, Halsey revealed they think Stranger Things' Brown would be "great" playing them in biopic, considering their "uncanny" appearances.
"I mean, it's kind of uncanny how much we look alike," the singer said. "It's like, 'Oh, no. We actually just look like sisters.' "
One day later, Brown shared a snippet of the interview to her Instagram Story and confirmed she was game, writing "sooooo down."

Reese Witherspoon & Kelsea Ballerini
"We met several years ago at the Christmas tree lighting at the White House," the singer recalled of her first run-in with Witherspoon on a 2022 episode of PEOPLE (The TV Show!). "We were backstage, and I just said, 'You know, people say I look like you, and I'm obsessed with you.' "
Ballerini added that, since then, their "paths have crossed so much, and we've become really lovely friends."
"I'm able to call her if I have a question or need some encouragement or advice. She's a true girls' girl," she said.

Chris Pine & Joey Lawrence
Whoa! Do you see a resemblence between the two stars? Someone did in March 2022.
"I was out this weekend, went to a couple parties and it was alright," Pine recalled on a post-Oscars visit to Jimmy Kimmel Live!. "I was at one and I was about to go and this guy stopped me and he's like, 'I know you.' I was like, 'God, this again' — and he's like, 'Joey Lawrence!'"
After telling the fan he was "not quite" right about his guess as to who he was, the stranger said to Pine, "C'mon man, tell me who you are!" Poking fun at celebrities he's been mistaken for in the past, Pine responded, "Chris Evans, Captain America" as he went in for a handshake.
"And to top it all off he goes, 'That's my man,'" the actor said.
This isn't the first time Pine's been mistaken for another Hollywood actor. "I've gotten Ryan Reynolds, [Chris] Pratt, [Chris] Hemsworth, Matt Damon," he listed, "But it was a first for Joey Lawrence."

Megan Fox & Adriana Lima
The two women had a cheeky exchange in the comments of a post Lima shared to her Instagram feed in July 2021.
Alongside a photo split of herself and Fox in full glam makeup, the model wrote, "⚡️💋 @meganfox if you ever need a body double in one of your movies , hit me up ☎️ ⚡️ my only request is ... We share the same makeup artist @patrickta 💁🏻♀️💋⚡️."
Fox didn't miss a beat in the comments, writing, "But what if I need a girlfriend ... can I hit you up for that as well? 💜"
"Patrick can still be involved somehow. He can do our makeup when I take you to Nobu," teased the Jennifer's Body actress.
"It's a date see you tonight at Nobu," the former Victoria's Secret Angel replied, alongside two flame emojis.

Demi Lovato & Kacey Musgraves
Both incredibly talented singers? Check. Both stunning in shimmering orange getups? Check. Both rocking great brows and perfect middle parts? Check. We're not exactly "Confident" in telling Lovato and Musgraves apart in this one ...
11of 55
Kyle Richards & Kacey Musgraves
On the other hand, "so many people say that [Kacey Musgraves] & I look alike. Have to agree," Richards wrote on Instagram following a May 2019 episode of Real Housewives of Beverly Hills. She also shared a pic of Musgraves in her blonde, Barbie-inspired Met Gala getup, writing, "Then my friend pointed out how Kacey looks like my niece Paris Hilton here. Who people think looks like me but blonde. So maybe Kacey is a long lost relative."
12of 55
Kate Mara & Isla Fisher & Anna Kendrick
Mara told PEOPLE she gets recognized in airports — but usually not as herself: "People usually don't think I'm me. They think I'm Anna Kendrick or Isla Fisher. They'll say, 'You were so good in Wedding Crashers!' And I'm like, 'Thank you!'" Kendrick poked fun at their frequently mistaken identities in a 2014 tweet, joking, "People get us confused. Then we showed up to dinner in the same jacket. So now we can never hang out again"
13of 55
Dylan McDermott & David Schwimmer
We totally get why Dylan McDermott has been confused for David Schwimmer (by none other than Piers Morgan): They're both tall, dark and handsome, and both starred on iconic '90s series.
14of 55
Hilary Duff & Victoria Pedretti
Fans are flipping out over the similarities between You season two star Victoria Pedretti, who plays the onscreen love interest (literally named Love) of Penn Badgley's Joe, and Hilary Duff.
To add another layer to the actresses' look-alike comparisons, Duff previously shared the screen with Badgley - in another role where his character wasn't quite what he seemed - as girlfriend Olivia Burke in season three of Gossip Girl. Anyone remember their steamy ménage à trois with Vanessa?
15of 55
The Property Brothers & Zachary Levi
Who knew the Property Brothers were triplets? Okay, so Zachary Levi is not actually related to the identical Scott twins, Jonathan and Drew - but he certainly looks like he could be. (Anyone else think that Jonathan's relationship with Zooey Deschanel looks a lot like the real-life version of Midge and Benjamin in The Marvelous Mrs. Maisel?)
16of 55
Ryan Reynolds & Kate Beckinsale
"I look exactly like Ryan Reynolds," Beckinsale told host Jimmy on The Tonight Show Starring Jimmy Fallon. "Like in a shocking way. Like, when sometimes, I see a bus going by with a poster on it I think, 'Damn, I look hot. Oh, wait, that's not me. Also, I've never done that movie.'"
When Reynolds stopped by the Today Show, cohosts Hoda Kotb and Craig Melvin showed the star the clip of Beckinsale, and he couldn't help but agree.
"It is like looking in a mirror," he joked, before saying, "This has been something that I've heard for a long time. Other people have said it to me as well."

Ed Sheeran & Prince Harry
Prince Harry left a group of schoolgirls giggling after they asked him if he was the real royal - or pop star Sheeran. As he approached the line of about 70 flag-waving pupils on Commonwealth Day in 2017, the prince stopped to speak to 12-year-old Tiya Thornton, who told him that he looked like fellow redhead Sheeran. "Are you the real Prince Harry?" Tiya asked the prince, to which he replied, 'Yes, the other one is Ed Sheeran.' "
The guys talked about their common ginger thread in 2019, in a PSA they filmed together for World Mental Health Day.
18of 55
Rupert Grint & Ed Sheeran
The prince isn't the only one. Harry Potter's Grint told James Corden that nearly 50 percent of fans he meets thinks he's Sheeran. "If someone spots me, I could go either way," he shared. In fact, even other celebrities have trouble differentiating the pair: Grint said British singer-songwriter Leo Sayer once made the mistake. "He came up to me and said he loved my music, of course thinking I was Ed," said Grint, adding, "I play along." What likely adds to the confusion: the actor appeared in Sheeran's 2011 music video for "Lego House."
19of 55
Matt Bomer & Henry Cavill
The piercing eyes, the strong jaws, even the parts of their hair - Bomer and Cavill look like they could be brothers. And they've even been up for the same roles: in 2015, Bomer revealed he auditioned for the part of Superman in Man of Steel, a role that ultimately went to Cavill.
20of 55
Allen Leech & Niall Horan
Despite their age gap, the Downton Abbey star is often reminded of his resemblance to the singer. "People do it all the time," he said on The Late Late Show of his doppelgänger being brought up. "It happened, I think, at the start of Downton, people were like, 'Oh my God, Niall is on the show!' on Twitter."
"It's very flattering to me. I'm 38, he's 26," Leech added.
The actor went on to mention the August 2019 tweet in which Horan recounted getting called out as his look-alike at a restaurant. "Waiter just said to me 'Did anyone ever tell you that you look exactly like the guy from Downton Abbey?' @Allenleech," Horan wrote.
"I'm guessing Niall had a really big night. If he's starting to look like me, I'm worried. Moisturize more, Niall," Leech joked of the incident on the late-night show.

Courteney Cox & Demi Moore
"Who's who 👯♀️," Demi Moore captioned this photo of herself with actress Courteney Cox on Instagram.
Cox commented on the twinning shot, writing, "Haha! I'll have to send you a pic that I was even confused by 💕"
Social media users also saw the uncanny resemblance and shared their thoughts in the comments.
"Are you relatives? 😊😊😊," one user wrote.
"Sisters?!?" another added.
22of 55
Katharine McPhee Foster & Sophia Bush
In December 2018, McPhee posted a hilarious video to her Instagram from a red carpet event years ago, where she was accidentally mistaken for the One Tree Hill actress. In the clip, a reporter calls over McPhee for an interview but refers to her as "Sophia" - which it seems McPhee does not initially hear - and then proceeds to say, "You're in One Tree Hill."
McPhee was understandably confused at the time, but years later, decided to capitalize on the error. "if there's ever a @sophiabush biography, y'all know who to call…" she jokingly captioned the video.
"I legitimately cannot stop laughing," Bush replied. "Also, not fair that it doesn't go the other way! No one's ever heard me singing and said "oh you sound just like Katharine McPhee" dammit!!"
23of 55
Sarah Hyland & Lucy Hale
Maybe they've never been the most obvious faux twins, but when Hale posted this photo in September 2018, the brows and bone structure said it all.
"Anyone tryin to cast some sisters?" she captioned her Insta.
24of 55
Mila Kunis & Sarah Hyland
Because of that seven-year age difference, Kunis really could be Hyland's big sister - which helped when the Modern Family actress dressed up as Kunis's That '70s Show character, Jackie Burkhart, for Halloween in 2010. "People say I look like Mila," she told Cambio. "I've always wanted to be Jackie for Halloween, so [I] just did it."
25of 55
Meghan Markle & Joanna Gaines
Squint and you might see the Fixer Upper star bears a resemblance to Prince Harry's leading lady. From their flawless waves to their picture-perfect smiles, Joanna Gaines and Meghan Markle could be twins ... or really distant relatives (depending on who you ask.)
26of 55
Carla Bruni & Bella Hadid
We're seeing double! Carla Bruni, the Italian-French '90s supermodel and former First Lady of France, and Bella Hadid are well aware of their twinning status. Bruni shared a look-alike selfie on her Instagram to share the moment with followers.
27of 55
Zach Braff & Dax Shepard
Separated at birth? Alex, Inc. star Zach Braff shared a face swap of the look-alike pals to Twitter that Shepard's wife, Kristen Bell, took a few years back. "I'm gonna get this put on a T-shirt," Braff joked in the caption. Shepard played along, admitting, "For me, it's really the pictures in the left [column]. I mean, it almost appears that there was no swap there." We're thinking it might be time for Braff to go blonde…
28of 55
John Mayer & Antoni Porowski
Queer Eye star Porowski posted an Instagram of himself posing exactly like Mayer with the caption, "'I dunno, guys, I just don't see it.'" Apparently, some of his followers were confused by his sarcastic caption, so he clarified by posting a side-by-side photo of his picture next to Mayer's-and yes, they're basically identical twins who were separated at birth.
29of 55
Gus Kenworthy & Richard Madden
Olympic freestyle skier Gus Kenworthy is a king in his sport. And it turns his celebrity doppelgänger is a king, too - or was, anyway - in the North. Of Westeros, that is. As the internet noted, and Kenworthy called out on his own Twitter and Instagram Story, the athlete shares an undeniable resemblance to Scottish actor Richard Madden, perhaps best known for playing the ill-fated Robb Stark in the early seasons of Game of Thrones. "Uh oh," he called out to Madden on social media, "they're on to us…"

Tiffani Thiessen & Alexandra Daddario
The 90210 alumna and the Baywatch reboot star - who both appeared on White Collar - share the same piercing blue eyes and dark locks.

Harry Connick Jr. & The Property Brothers
While filming a segment for Harry, Connick Jr. and Property Brothers star Jonathan revealed they're frequently told they're one another's celebrity doppelgängers. "It's funny, we're twins, but no one in all my life has ever said I look like you," Drew said of Jonathan and Connick Jr.'s resemblance. "But people say it all the time that he does." Jonathan added: "I get more messages [from people] online who say they swear we were split at birth." Connick Jr. couldn't help but agree. "I can really see it now," he said.
32of 55
Bella Hadid & Jennifer Lawrence
One is on top of the fashion world, the other the acting scene. But dominating their respective industries isn't the only thing Hadid and Lawrence have in common: they look alike. When asked how often she's compared to the Oscar winner, Hadid told Fashionista: "Multiple times a day. Probably today it's already happened like five times."
33of 55
Brie Larison & Natasha Bure
Candace Cameron Bure's daughter Natasha made headlines for her performance on The Voice (it even got Adam Levine's attention!). However, you'll be forgiven if you've been confusing her for another famous lady: Oscar winner Brie Larson. They both have that same sweet-but-slightly-mischievous smile, a similar set of eyes and nearly identical heads of dirty blonde hair. Now, we just need to the two to meet and pose for a selfie.
34of 55
Jason Sudeikis & Ed Helms
On Conan, Sudeikis revealed that he's constantly mistaken for his Vacation costar. "Ed Helms and I, I think, get confused quite a bit, the two of us," he said. The actor added that he isn't bothered by the mix-ups because "I'm in a good place in the sense that mine is a really nice, funny, smart guy." Sudeikis even embraced an awkward run-in at the White House Correspondents' Dinner when a fellow attendee who had asked for a picture seemed taken aback when he said his name was "Jason." "Did you think I was Ed Helms from The Hangover?" the star recalled asking the fan. "Yes, but it's OK," she replied. "You look enough like him."
35of 55
Ashley Graham & Eva Mendes
The actress and the Sports Illustrated cover girl are undeniably united in hotness. The ladies' flawless glowing skin, thick brunette waves and can't-look-away brown eyes have us wondering if they're really long-lost sisters. If so, their gene pool might just be a national treasure.
36of 55
Matthew Morrison & Paul Ryan
Whether it's the nose, the ears or the smile, there's no denying that politician Paul Ryan shares a certain something with former Glee star Matthew Morrison.
37of 55
Jared Haibon & Ashton Kutcher
Kutcher's wife Mila Kunis had to get a side-by-side comparison of her husband and equally hunky Bachelor in Paradise contestant Jared Haibon. "I'm trying to figure out why mila is making me take this picture @ashleyiaco who are you? And who is this guy?" Kutcher wrote on Twitter when he shared the snapshot. But Paradise contestant Iaconetti was the first to notice their equally chiseled cheekbones and jaws. On the show, she said Haibon looked like a mix between Kutcher and Joe Jonas.
38of 55
Alicia Silverstone & Maggie Lawson
Silverstone and Lawson are friends because they "both know what it's like for people to be jealous of [them]." Okay, we can't confirm that, but the actress' near identical features do inspire envy.
39of 55
Ana Gasteyer & Kathryn Hahn
Gasteyer brought the laughs on Saturday Night Live in the late '90s. Or was that Hahn? The actresses' lush brown locks, wide smiles and rosy cheeks make it hard to tell them apart. Add this to the list of similarities: Before heading to Hollywood, both women studied at Northwestern University. Coincidence or cosmic attempt to reunite long-lost twins? All signs point to the latter.
40of 55
Melissa Benoist & Blake Lively
Supergirl Benoist could be Lively's twin with her bright eyes and blonde hair. And the former Gleek has another weird connection with the starlet: She was once married to her Glee costar. His name? Blake Jenner!
41of 55
Julie Bowen & Elizabeth Banks
The funny women are both proud blonde mamas and are even within an inch of each other's height. Surprisingly, when Elizabeth Banks guest-starred on Modern Family she didn't play a relative of Julie Bowen's character.
42of 55
Amanda Steele & Ashley Benson
Ever since the MakeupbyMandy24 star ditched her brunette hair, she's been mistaken for the Pretty Little Liars star everywhere she goes (we assume). Their gorgeous faces are almost interchangeable, which isn't really a problem because when you look that good, two is definitely better than one. Benson and the YouTube sensation are also both California girls, and although she isn't still a high schooler like Steele, she does play one on TV.
43of 55
Amal Clooney & Anne Hathaway
Ms. Hathaway and Mrs. Clooney have more than one thing in common: Between their full lips, dark hair and big, brown eyes, the actress and attorney could almost be sisters. "I hope that I become half the woman that she is - she's so accomplished, and it's so thrilling to look at someone and be like, 'Oh, you really are making the world a better place,'" Hathaway told Extra of her doppelgänger.
44of 55
George Clooney & Guillermo Zapata
Hate to break it to you, George: You no longer have a monopoly on silver-fox good looks. The actor's eerily identical doppelgänger is Guillermo Zapata, an Argentinian male model who co-owns SUR restaurant in West Hollywood with The Real Housewives of Beverly Hills star Lisa Vanderpump. But sorry ladies - Cloney, as he's been dubbed, is happily married, just like his prototype.
45of 55
Chris Soules & Scott Speedman
Wait, did they cast former Felicity heartthrob Speedman to be the Bachelor? Nope, that eye candy who went looking for love on the ABC reality series just happens to be equally good-looking, with chiseled facial features and the bod to match. We'd accept a rose from either.
46of 55
Darren Criss & Kit Harington
Cute curls, dreamy eyes: We swoon equally over Glee's Criss and GoT's Harington.
47of 55
Mick Jagger & Harry Styles
British? Check. Stylish? Double check. Both Jagger and Styles possess a certain swagger, and while the Rolling Stones singer is old enough to be the One Direction heartthrob's granddad, in the past their similar good looks have had some overzealous bloggers suggesting the boy bander could play Jagger in a biopic.
48of 55
Amy Adams & Isla Fisher
They're equally red-hot with their long copper locks. But though Fisher has big brown eyes and Adams's are ocean blue, people still get the two stars confused. "I get [mistaken for] Isla Fisher all the time, still," Adams told Vanity Fair. "When I'm with Isla, we both look at one another and … I get it but I don't get it."
49of 55
Nina Dobrev & Victoria Justice
Comparisons between Vampire Diaries babe Dobrev and Victorious star Justice are nothing new for the brunette beauties. "It's been happening forever!" Justice told The Huffington Post. "I think it's flattering. She's so pretty, so it's very nice to be able to say that!"
50of 55
Chace Crawford & Ian Somerhalder
Either way, you can't lose: Both Crawford and Somerhalder have smoldering baby blues, cool coifs and wickedly handsome smiles. Despite their six-and-a-half-year age difference, the two could totally pass for twins.
51of 55
Jessica Chastain & Bryce Dallas Howard
The foremrThe Help costars look so similar that there was once a rumor that Chastain and Howard were secretly sisters! And though it isn't true, Howard's dad Ron Howard did once mistake Chastain for his own daughter. Chastain even made a TikTok poking fun at their frequently mixed up mugs.
52of 55
Zoe Saldana & Thandiwe Newton
"I'll be walking down the street and I'll have people go, 'Hey, Thandiwe Newton!'" Saldana revealed on an episode of The Late Late Show with Craig Ferguson. Can we get these two cast as sisters soon?
53of 55
Katy Perry & Zooey Deschanel
Yes, they're both musical. Yes, they both have dark hair and big, pretty eyes. Yes, they've been in the same place at the same time. And yes, it sounds like Deschanel is over the Perry comparisons. "I'm happy that she's famous enough now that she's not going out and being mistaken for me," the New Girl famously told MTV.
54of 55
Jeffrey Dean Morgan & Javier Bardem
It's possible Morgan got his role on Grey's Anatomy because the show's creator, Shonda Rhimes, thought she was hiring Bardem. Morgan is basically everything The Counselor star is, with that olive complexion and sexy scruff - he's just missing the Spanish accent (but that can be faked, right?).
55of 55
Leighton Meester & Minka Kelly
Those almond eyes! Those chestnut waves! That girl-next-door smile! Yes, Gossip Girl cutie Meester and Friday Night Lights beauty Kelly have all the makings of bombshell look-alikes - which is why they were so well-suited for their 2011 thriller The Roommate, in which Meester actually posed as Kelly.
