Quite hectic list! As a nerd, I would tend to have a crush on Portman, just as I once had on Princess Lea. However, when I saw her once, it was rather disappointing!
Never heard of Emma Stone. I googled and I found out she worked in a movie about zombies.... well, if she were not a zombie, that would explain why she caught your eyes! Jokes apart, she looks very sexy indeed!
Finally, Audrey Hepburn: I simply love Breakfast at Tiffanys. She was amazing and her talent made her even sexier! I definitively have a crush on her.
But do not forget another star from the past. Grace Kelly was the queen!
