Celebrity doppelgangers: What celebrity do I look like?

This week is celebrity doppelganger week on the social networking site Facebook. Facebook users are supposed to change their profile pictures to that of celebrity who they think looks like them.

It's likely the most popular theme Facebook has created yet, as the Internet is abuzz with people trying to figure out who their celebrity twin might be.

One easy way to find out is just to ask the person sitting next to you or think back to a time when someone told you that you reminded them of someone else (this has probably happened more than once).

However, there are plenty of Web sites that offer a celebrity look alike finder. You simply upload a photo of yourself and it finds your celebrity doppelganger.

Check out the links to the left to find your celebrity look alike.
