Right now I have one on Davey Havok (from AFI). -- which is odd, because people used to say that I looked like him, but even cuter! I wore make up as a guy and did my hair Davey Havok style several times (well, the style on his new album, anyway). The other person people used to say I looked like was Robert Smith (The Cure) and Edward Scissor-hands (Johnny Depp -- whom I have crush on, too).
I can't think of any famous girls that I have a crush on right now. I did in the past, but no one recenly has caught my eye (I also don't watch much TV or Movies).
And, now that I'm my real self -- a girl -- I don't know if I actually look like someone famous (which could be a good thing, because that just means I'm more original).
