Katy Perry and Zooey Deschanel are obvious look alikes, but there are some celebrities who bear an uncanny resemblance you may have never noticed. We’ve rounded up 10 of the most surprising celebrity dopplegangers:

Katy Perry and Tessa Virtue
Katy Perry is often said to be a dead ringer for Zooey Deschanel, but we see quite the resemblance between the “Dark Horse” singer and Canadian Olympian ice dancer Tessa Virtue.

Amy Adams and Tessa Virtue
Another celeb Virtue resembles? Amy Adams. Just think, if Tessa had lighter hair, she and Amy could practically be long-lost sisters (especially judging by their side profile!).

Ke$ha and John Travolta
While many people seem to think Ke$ha and Blake Lively look alike, we see a clear resemblance between the “Timber” singer (pre-nose job) and John Travolta, especially when Ke$ha is bare-faced.

Blake Lively Colbie Caillat
Speaking of Blake Lively, we are seeing some serious similarities between her and singer Colbie Caillat. Both blonde, both tanned, and both beautiful; the two not only share the same looks, but similar taste in fashion. Or perhaps Colbie is just taking style cues from Blake–she has, after all, been seen channelling the Gossip Girl star’s red carpet style.

Mischa Barton and Elijah Wood
These two could easily pass for fraternal twins, no?

Naya Rivera and Kim Kardashian
Is it just us, or are Naya Rivera and Kim Kardashian looking freakishly similar lately? Perhaps it’s the lighter locks, or the sexy pout, but either way, we think the Glee star could easily transition into Keeping Up With the Kardashians.

Scarlett Johansson and Christopher Walken
When we saw this photo of a young Christopher Walken beside a pic of Scarlett Johansson, we immediately wondered if the two were distant relatives. We just hope Johansson ages a bit more gracefully than Walken did…

Miley Cyrus and Justin Bieber
We started to see some similarities between the Biebs and Miley when the songstress chopped off her long locks. It became even more obvious when Cyrus imitated Bieber in a skit on SNL. But we could have never prepared ourselves for this face mash-up. Kudos to the genius who created this Photoshop masterpiece.

Justin Bieber and Paul Wesley
Bieber’s other doppleganger? Paul Wesley. We could easily see Justin playing a young Stefan on The Vampire Diaries.

Selena Gomez and Jacquie Lee
Um, hello twinsies! When we first saw Jacquie Lee on season five of The Voice, we had to do a double take. Was Selena Gomez posing as a 16-year-old girl from New Jersey looking to break in the music biz, or was this just a freaky case of the dopplegangers? Apparently, the latter was true. We wouldn’t be so convinced if it weren’t for Lee’s vocals–the girl has some chops that arguably surpass Gomez’s (no offense, Selena!).
