Today I came across this site from My where you upload a pic of yourself and have the site search it’s celebrity databases for a facial match.

My top 5 matches:
1. Reika Hashimoto
2. Halle Berry
3. Ninet Tayeb
4. Zhang Ziyi
5. Bipasha Basu

Quite a multicultural bunch eh? Can’t say that any of them look close to me.
Give the site a try, who knows who you look like?
