I get Maggie Q and I agree... except for the small nose and the tin body. I've picked some pictures that are similar. I also have something of Karlies cheekbones.
Emma Watson. I got asked for an autograph by an airsteward once, thinking I was her. Our bodies are not at all similar, but we are similar facially. Her eyebrows are closer to her eyes than mine and my lips are slightly fuller, but otherwise we're very similar looking.
I posted this picture on my FB page for "doppelganger week" and got loads of comments from people who actually thought it was me, haha.
I actually heard several times that I look like Pocahontas (when I had my natural hair color still - dark brown - and quite a bit longer). It's my fav Disney character, so I'll take it LoL
I have some Kirsten Dunst, Jennifer Morrison (Cameron from House) going on. Love to get Keira Knightley. For some reason black people think I look like Avril Lagvene. No racism implied, just no one of other culture ever says that to me.
