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.

Cindy Crawford & Queen Letizia
It makes perfect sense that one of the most gorgeous supermodels of our time looks exactly like a member of the Spanish royal family.

Chris Martin & Jake Paltrow
Add some scruff and a buzzcut, and Gwyneth Paltrow's brother looks a lot like her consciously uncoupled husband. File that under things you can't unsee.

Jennifer Lawrence & Helen Mirren
Jennifer Lawrence was being compared to young Helen Mirren so frequently that Jon Stewart asked her about it on The Daily Show.

Fergie & Kirstie Alley
If Timothy Olyphant and Kirstie Alley got married, we'd have two duplicate couples. How do we make this happen?
