13 Celebrity Doppelgangers

Facebook's "celebrity doppelganger week" has turned countless profile photos into pictures of celebrities—but what if the celebrities themselves want to get in on the fun? PopEater offers up some suggestions for famous lookalikes:

• Zooey Deschanel: The actress should consider posting a picture of singer Katy Perry.
• Christina Aguilera: Add some pants, and Lady Gaga looks just like her.
• Zac Efron: He's basically interchangeable with fellow pretty boy Chace Crawford.
• Ed Westwick: Crawford's Gossip Girl costar could post a picture of Robert Pattinson.

• Selena Gomez: Looks just like fellow Disney teenybopper Demi Lovato. What a surprise!
• Nicole Kidman: Could go with a picture of friend and fellow Aussie Naomi Watts.
• Javier Bardem: There's no way he and Jeffrey Dean Morgan weren't separated at birth.
