1. Keira Knightley & Natalie Portman
As far as celebrities who look like other celebrities go, Keira Knightley and Natalie Portman definitely fit the bill. In Star Wars Episode 1: The Phantom Menace, Knightley played Portman’s lookalike and it was said that when both were in full makeup, even their mothers had a difficult time telling them apart.
2. Amy Sedaris & Kristin Chenoweth
These two actresses both have the wonderful ability to look either crazy or beautiful on any given day. They look like they are sisters with the same exact smile and very similar eyes. I think the dimples play a major role in the similarity of their faces.
3. Kyra Sedgwick & Julia Roberts
To me, these two lovely ladies look like one in the same! Their faces are remarkably similar; they look like they could be twins! They have the same eyes, nose and distinctive mouth. They also share a lot of the same mannerisms. These two are definite doppelgangers.
4. Oliver Jackson Cohen & Jake Gyllenhaal
Whoa! Could these two possibly look any more alike? Don’t get me wrong, I’m definitely glad that there are two such handsome looking men in the world! Their eyes, hair, eyebrows and facial hair and bone structure are nearly identical, it’s amazing!
5. Johnny Depp & Skeet Ulrich
Personally, I wish EVERY guy looked like Johnny Depp, but Skeet Ulrich comes about as close as we’re going to get, I think! Both of these men have those gorgeous cheek bones. While their jaw lines might be a bit different, their facial hair and those to-die-for eyes really show their similarity.
6. Eric Dane & Leonardo DiCaprio
Look at these two handsome men! While they don’t look as much alike as some of the others on the list, they definitely have a similar look about them. It’s hard to believe they aren’t related! I think it’s the shape of the face and the similar hair cut, but it definitely has a lot to do with those pretty blue eyes of theirs!
7. Amanda Seyfried & Dakota Fanning
Amanda Seyfried and Dakota Fanning are two of my favorite actresses and they look remarkably alike! I think it is entirely because of the innocent looking faces with the big, bright blue eyes. These two are gorgeous girls and talented actresses with bright futures ahead of them.
8. Elijah Wood & Daniel Radcliffe
To be honest during my early years, I believed that Elijah Wood and Daniel Radcliffe were the same person. However, can you really blame me? They share the exact same big blue eyes, same face structure and body type, they are basically a facsimile of each other. Just take a look yourself!
9. Heath Ledger & Joseph Gordon- Levitt
Their unmistakable similarity really makes me wonder if they are somehow related. Although Heath Ledger has more of a prominent forehead and nose, the insignificant differences have no affect on their uncanny similarities. If one day I got the chance to see them both in real life, I would think that they are the same person just on a different day.
10. Ian Somerhalder & Chace Crawford
Ian Somerhalder is no stranger to the idea of dopplegangers, but did was he aware that he has one in real life? Both of the CW co-network stars share the exact same eminent eyebrows, piercing eyes and flawless jawline. Good thing they are not on the same show, because that would cause a whole lot of confusion!
11. Kris Humphries & Taylor Lautner
You might know one of them from his short marriage with Kim Kardashian and the other from The Twilight Series. However, have you ever put a picture of the two of them side to side? If you have you were probably shocked at the ridiculously apparent similarity between the two of them. They really do have the same werewolf-like appearance that is hard to miss.
12. America Ferrera & Jordin Sparks
These two celebrities are so similar that you would probably have a hard time pointing out the differences between their facial characteristics on the pictures. The two talented starts share big luscious lips, bronze skin color and brown eyes. You would have to be blind to deny, their strong resemblance.
13. Emily Osment & Carrie Underwood
How did I not see that these two people are the exact replica of each other in the past? These two gorgeous ladies could seriously pass for identical twins. It really is a small world for connected people in the same business industry to look so much alike!
14. Lauren Conrad & Carmen Electra
You can't really make a list of celebrity look a-likes without mentioning Lauren Conrad and Carmen Electra. I wouldn't call these two split-images of each other but the similarity is definitely there. They could pass for sisters without a problem!
15. Tilda Swinton & Conan O'Brien
You though that celebrities of the same gender were the only ones with secret twins? Well you were greatly mistaken, just take a look at Tilda Swinton and Conan O'Brien, they are like the same person born twice. Even the stars themselves are shocked at their similar appearances. Conan O'brien once said that he would like Tilda to play his in his autobiography and Tilda herself didn't refuse! A couple of these pairs I had never really realized looked so much alike. I found many, many more lookalike duos than I had expected to. Some of these folks look so much alike that if they were swapped into their counterpart's role in a movie, I may not even notice! What two celebrities do you think look the most alike? Do you know of any celebrity lookalikes that I missed?
