Last year, I interviewed Rachel Bilson about her biggest beauty regret. I love Bilson, having been a fan of  The O.C.  as well as  Hart of Dixie  (RIP). But because I hadn't had coffee yet or because I had a serious mental lapse, I called the  Take Two  star Leighton Meester to all my colleagues. I know they're not the same person, but they were both huge teen stars; I was also a huge fan of Meester in  Gossip Girl . For some reason — presumably because of their pretty remarkable resemblance — I totally mixed them up in my head. That got me thinking about all the other celebrities who look so much alike that it's scary. Some have the same hair, others have the same facial features — many have both. And one pair of celebs is even 50 years apart! But seeing these duos is like seeing double.
