This story originally ran on January 18, 2015. In honor of National Look Alike Day, we're bringing it back!It's almost eerie how much some celebrities resemble each other. Just look at Avicii and Taylor Swift over there. He's a Swedish EDM DJ. She's an American pop star. Yet, the two of them could easily share a passport or star in a madcap series of detective moviesà la Mary-Kate and Ashley 2.0. We bet these two performers could solve any crime by dinnertime.
Once you see these celeb duos side-by-side, you'll have trouble believing that they're not related. That's the beauty of these famous doppelgängers though: Double the pleasure, double the fun. They're truly the gift that keeps on giving.
Selma Blair & Kris Jenner
There's a reason Selma was cast to play the former Mrs. Kardashian in The People v. O.J. Simpson!
Taylor Swift & Avicii
Is Taylor Swift moonlighting as a Swedish DJ? I mean, has anyone ever seen them both in the same room?
Sarah Hyland & Mila Kunis
When the Modern Family star is brunette, she's a dead ringer for Mrs. Kutcher.
Cindy Crawford & Queen Letizia
It makes perfect sense that one of the most gorgeous supermodels of our time looks exactly like a member of the Spanish royal family.
Elijah Wood & Daniel Radcliffe
The next time you watch Lord of the Rings or Harry Potter, pretend that Frodo and Harry are long-lost twins, each going on their own magical adventure.
Chris Martin & Jake Paltrow
Add some scruff and a buzzcut, and Gwyneth Paltrow's brother looks a lot like her consciously uncoupled husband. File that under things you can't unsee.
Anne Hathaway & Amal Clooney
Many people have been quick to point out the similarities between the actress and Clooney's new wife.
Natalie Portman & Keira Knightley
Knightley's close resemblance to Portman earned her a role as Queen Amidala’s decoy in Star Wars: The Phantom Menace.
Jennifer Lawrence & Helen Mirren
Jennifer Lawrence was being compared to young Helen Mirren so frequently that Jon Stewart asked her about it on The Daily Show.
Josh Duhamel & Timothy Olyphant
Add in Johnny Knoxville, and you've got yourself some chiseled-jaw triplets.
Leighton Meester & Minka Kelly
Meester and Kelly's strong resemblance allowed them to costar in Single White Female 2.0, The Roommate.
Olivia Wilde & Alexis Bledel
Alas, they are not the subjects of the film Big Eyes.
Fergie & Kirstie Alley
If Timothy Olyphant and Kirstie Alley got married, we'd have two duplicate couples. How do we make this happen?
Tilda Swinton & David Bowie
They could form a killer double act called the Thin White Dukes.
Ryan Gosling & Ranbir Kapoor
Hey girl, just look at those identical face shapes.
Heath Ledger & Joseph Gordon-Levitt
Here's a photo of them together on the set of 10 Things I Hate About You to make this moment even more punch-you-in-the-gut.
Victoria Justice & Nina Dobrev
Together, they could take over Nickelodeon, The CW, and then the teen world.
Jordin Sparks & America Ferrera
United by a megawatt smile.
Jennifer Garner & Hilary Swank
But, only one of them can be married to Ben Affleck.
Tom Cruise & Peter Facinelli
And, if you'd like to see a brown-eyed version, check out Sean Faris or Niko Pepaj. The world really is your oyster, in terms of Tom Cruise doppelgaängers.
Aishwarya Rai & Marion Cotillard
Perhaps India and France's most renowned actresses of their generation.
Dominic West & Billy Crudup
Take a vacation in those big, brown, soulful eyes.
Scarlett Johansson & Amber Heard
They're down for the pout.
Leonardo DiCaprio & Dane DeHaan
Ol' Blue Eyes and Young Blue Eyes.
Thandie Newton & Sherri Saum
Only one of them is British, though.
Ashley Madekwe & Amber Stevens
Let's hope Madekwe never seeks Revenge on the 22 Jump Street star.
Tom Hardy & Logan Marshall-Green
Additional fun fact: Marshall-Green also has a twin named Taylor.
Katy Perry & Zooey Deschanel
Baby, you're both fireworks.
Javier Bardem & Jeffrey Dean Morgan
There's a Spanish version and an American version.
Rose Byrne & Shannon Woodward
They're both gifted comedians, too.
Jeffrey Tambor & Pope Francis I
George Bluth and the Pontiff: Separated at birth?
