#7 - Emma Watson
Hermione Granger! My how you've grown!

Since the Philosopher's Stone when Hermi was but a young rat faced mud-blood, to the Chamber of Secrets when she began to get an air of cuteness about her. She wasn't anything special, because she was still a kid, but even my mum could see the potential that Emma had at the time.

Along came Prisoner of Azkaban, and Emma was beginning to become a woman. Plus she packed a killer punch and smashed that little pansy Draco fair in the face. I really cannot handle that kid.
Emma really came into her own however, in the Goblet of Fire. She walked out in the ball gown, and the D-Train fell even more in love with the girl.

Obviously there is plenty of time for her to go bad, hit the booze and drugs, and become a washed up child actor like the rest of them seem to do. But I'll take my chances on this one.
So what if she's only 16.... it's only illegal if you get caught. Plus, she's drinking beer, that can only be a good thing.

Next: She may have been the first woman on Earth, but she was always going to take a wrong turn.
