It's almost eerie how much some celebrities resemble each other. Just look at Avicii and Taylor Swift over there. He's a Swedish EDM DJ. She's an American pop star. Yet, the two of them could easily share a passport or star in a madcap series of detective movies à la Mary-Kate and Ashley 2.0. We bet these two performers could solve any crime by dinnertime.
Once you see these celeb duos side-by-side, you'll have trouble believing that they're not related. That's the beauty of these famous doppelgängers though: Double the pleasure, double the fun. They're truly the gift that keeps on giving.
