16 Celebs Who Looks Just Like Their Siblings — PHOTOS

One of the greatest American past times is discovering celebrity doppelgängers. Like eating peanuts and Cracker Jacks at a baseball game or seeing fireworks on the Fourth of July, there is nothing more patriotic than stalking the Internet for pictures of famous people who look just like other famous people — you know, like how there is more than just a passing resemblance between Katy Perry and Zooey Deschanel. Sometimes, these celeb lookalikes are in the form of other stars, sometimes their in the form of people desperate to look like said celeb (see: this crazy realistic Kim Kardashian doppelganger), and sometimes, it's celebs who look like their siblings.

Now, of course there's the whole "family resemblance" thing involving genes and science and biology and all of that fun stuff. Of course it's not surprising that two kids with the same parents (or at least one same parent) look like each other, but it's always fun when the similarities go beyond just kind of resembling each other. The best is when the stars practically share the same face on two different bodies. Creepy? It's pretty much like twinning in the Twilight Zone. You know, or Hollywood.

Check out 16 celebs who look just like their siblings below.
