1. Katy Perry and Zooey Deschanel
When pop star Katy Perry first became famous after the release of her second album in 2008, Zooey Deschanel was already a well-known actress, and comparisons between the two were immediate.
The New Girl star did not seem too happy about it: "It's a little bit annoying, to be totally blunt," she told MTV in 2009. "The only similarity that we have is that we look a little bit alike. I have met her before. She seems like a nice person. I'm happy that she's famous enough now that she's not going out and being mistaken for me."
2. Kit Harington and Christopher Abbott
With their dark curly hair, cool beards and brooding eyes, it looks like the British Game of Thrones star actually has an American twin - actor Christopher Abbott (Girls, Catch-22).
Some fans have also jokingly called Abbott the love child of Jon Snow and another dark-haired actor, Shia LaBeouf.
3. Logan Marshall-Green and Tom Hardy
When the Upgrade star first emerged on the scene, fans were struck by how much he looked like British actor Tom Hardy (The Dark Knight).
For Marshall-Green, who actually has a twin brother in real life, it wasn't a first-time experience: "I’d be honored to be in the same sentence as Tom Hardy. I’ve been a twin since the day I was born - fraternal, but we look a lot alike - so I’ve already been mixed up with another man my entire life."
4. Margot Robbie and Jaime Pressly
Some celebrity duos look so similar, we can hardly tell them apart. The I, Tonya star and My Name Is Earl alum look like sisters, even with a 13-year-difference between them (Pressly being the senior).
"We do look a lot alike," Pressly said of her first meeting with Robbie. "When she did the movie I, Tonya I was in the premiere... and you know, everybody's talking about the doppelganger thing so I was excited to meet her[...] and was like - if I look like you, that's fine with me."
5. Lake Bell and Amanda Peet
Bell spoke to The A.V. Club about being often mistaken for Peet, who she called "super foxy".

6. Zoe Saldana and Thandie Newton
The Avengers and the Westworld are often confused with one another, and it's not just fans who think they look alike. “My mom still thinks that I’m in Westworld,” Salanda joked on the Late Late Show with James Corden. “Years ago, [she] thought that I was in Traffic. ‘Mom, you did not give birth to Thandie Newton.’”
“I met Thandie at the Golden Globes a couple of years ago,” added the Avatar star. “I hugged her. I kinda scared her because I didn’t tell her why I was invading her space: I go, ‘Please tell me people confuse you for me.” And she goes, ‘Who are you?’”.
7. Javier Bardem and Jeffrey Dean Morgan
The Walking Dead star is often mistaken for the Spanish Oscar-winner, and he once even used their unusual resemblance to play a prank on Bardem:

Though they come from different industries - Ferrel being a successful actor and producer, and Smith is the drummer for the legendary Red Hot Chilly Peppers - the two look just like brothers.
The two even appeared on a hilarious 'drum-off' on The Tonight Show (which Smith "shockingly" won).
11. Lucy Hale and Selena Gomez
With the wavy brown hair and heart-shaped face, The Bold Type star and the pop singer could definitely pass as sisters. Hale herself said she often gets mistaken for Gomez:
"Usually, I would correct them, but I remember there was this one time, it was this older lady in an airport, and she was like, 'Can I get a picture with you?' I thought that she thought I was Lucy," Hale told Insider. "Afterward she started listing off the projects that she liked of mine and I quickly realized that she thought I was Selena. And I kind of just went with it because I didn't want to crush her dreams," she added.
12. Will Arnett and Patrick Wilson
While Arrested Development star Will Arnett is famous for his comedic roles, The Conjuring's Patrick Wilson made his start in Broadway musicals. However, their similar facial features and haircut make them look like they hail from the same family.

13. Alba Baptista and Alicia Vikander

14. Eva Mendes and Ashley Graham

The Friday Night Lights and the Gossip Girl stars, who are also real-life best friends, often get confused for one another.

16. Carrie Underwood and Emily Osment
Not only are singer Carrie Underwood and actress Emily Osment incredibly similar, they even share the same birth date - March 10 - with 37-year-old Underwood being nine years the senior.

17. Zach Braff and Dax Shepard
Actors Zach Braff and Dax Shepard are one of Hollywood's more famous Doppelganger pairs, and they also admit that they do look alike.

18. Selma Blair and Kris Jenner
Actress Selma Blair and reality super-mom Kris Jenner are naturally similar, and when Blair played Jenner in the TV drama The People v OJ Simpson: American Crime Story, she even further transformed into her.

19. Stephen Colbert and Bob Saget

20. Daniel Radcliffe and Elijah Wood
The two famous baby-faced actors appeared in the Lord of the Rings (Wood) and Harry Potter (Radcliffe) franchises around the same time, and comparisons between them were quick to follow.

21. Milla Jovovich and Linda Evangelista
Even though there is a 10-year difference between them, Jovovich and Evangelista look like sisters - very beautiful sisters.

24. Kiernan Shipka and Mckenna Grace
Shipka and Grace definitely look like sisters - so much so that Grace was chosen to play Shipka’s younger sister in an episode of Chilling Adventures of Sabrina.
And with Grace being only 14-year-old, she might grow to look even more like Shipka. Being the doppelganger fans that we are, we can only hope.
25. Jon Hamm and Fabio
OK so we know this sounds a bit funny, but once you see actor Jon Hamm's resemblance to the legendary Italian model Fabio, you cannot unsee it.
To be more exact, the Mad Men star looks just like Fabio - minus the long hair. They both have the same handsome facial features and even share the same half-smile.
26. Jennifer Connelly and Lily Collins
The two beautiful actresses look so similar that they were chosen to play a mother and daughter in the movie Stuck in Love (2011).

28. Henry Cavill and Matt Bomer

The two brunette actresses look so alike, that Hyland even told InStyle Magazine that they've agreed that's it's ok for them to pretend to be the other.

30. Kris Humphries and Taylor Lautner
Are Kris Humphries and Taylor Lautner the same person? We want to see proof that they aren't.

31. Bryce Dallas Howard and Jessica Chastain
The two redhead actresses are so similar, that even Howard's dad - Academy Award winner, director Ron Howard - once mistook Chastain for his daughter.

34. Zachary Quinto and Eli Roth
American Horror Story's Zachary Quinto and Inglorious Bastards' Eli Roth are so alike, one can easily confuse between them.
Luckily in recent years Roth has been mainly behind the camera, directing and producing, so the chances of mixing him up with Quinto are slimming down.
35. Wes Bentley and Cheyenne Jackson
The two square-jawed, handsome actors are often compared to one another, and in 2015 were even co-stars on American Horror Story: Hotel.
According to the actors, staff on set kept confusing between them, thinking (like we do) that they basically are the same person.
36. Amy Adams and Isla Fisher
Fisher and Adams are another famous red-haired doppelganger couple, and they get mistaken so often that during an appearance on Jimmy Kimmel Live Fisher presented a mock PSA - to remind viewers that she is not Amy Adams.
“We have totally different names, hence we are totally different people,” she said jokingly.
37. Jennifer Love Hewitt and Lacey Chabert
Both actresses first appeared together on '90s cult classic Party of Five, but back than Chabert was a child so the similarities between the two weren't so clear.

38. Natalie Portman and Keira Knightley
Portman and Knightley began their careers as child actresses in the '90s, and in 1999 Knightley even had a minor role in Star Wars: Episode I – The Phantom Menace thanks to her resemblance to lead actress Portman.

"He walked up to my wife[...] "She'd never met him. He grabbed her face and said, 'This is what you're going to be looking at in 15 years'." And we say - not a bad face to look at!
40. Kristen Stewart and Teresa Palmer
Australian actress Teresa Palmer made her Hollywood debut with The Grudge 2 in 2006, and her resemblance to the Twilight star was immediately noticed by fans.

41. Skylar Astin and Dane Cook
In black and white - or in color - fallen-from-grace comedian Dane Cook and Pitch Perfect star Skylar Astin look pretty much the same.

42. Drea de Matteo and Portia de Rossi
How similar are these two? With their blond hair, heart-shaped face and big smiles, they truly look like long-lost sisters. And they even have a similar last name!
In recent years de Rossi is sporting a short pixie cut, so her resemblance to de Mateo is a bit less obvious, but their facial features are still very much alike.
43. John Mulaney and Grant Gustin
SNL Comedian John Mulaney is often mistaken to The Flash star Grant Gustin - and with their similar boyish good looks, it's no wonder.
On Late Night with Seth Meyers Mulaney shared that when he complained to his wife about being mistaken for Gustin all the time, she just told him that he should be thankful to still be compared to a handsome, 28-year old actor (Mulaney being 10 years older).
44. Joel McHale and Ryan Seacrest
The former fellow E! Channel stars are one of the most well-known doppelgänger pairs on TV, and they often joke about it themselves.
And even McHale’s own son can't ignore the similarities between them: “When [my son] would see Ryan Seacrest on the air, my wife would go, 'Hey Eddie, who’s on the TV right now?' And he'd go, 'Daddy.' Ryan is a very handsome man so I take that as a great compliment. Sure, he’s 4’11,” but still."
