I've never found my doppelgänger, and that's perfectly OK because I'm very superstitious (thanks to my Filipino background and my mother). For those who may not know, stumbling upon your doppelgänger is actually pretty eerie. Not only is it downright creepy when you find one (they apparently cast no shadow and have no reflections in a mirror or water), but it's also considered a bad omen. According to mythology, if you see your friend's look-alike, it's a sign of impending illness or bad luck. But if you see your own? It's a death omen (!).
However, if you see a celebrity's doppelgänger — not someone like you or me who's blessed with celeb-status genetics; we're talking about a celebrity who looks like another celebrity — that's just plain exciting.
Everyone knows that Amy Adams and Isla Fisher look eerily alike, but they're not the only stars who do. Let's take a look at a few more dead ringers.
