4. Emma Watson
Born on: 15th April 1990
Sexy because: she's so cute! Actually, currently, she's sexy because of her daring haircut, which makes her look like the adult she's on the cusp of becoming!
Hottest Moment: Has little Emma actually had any hot moments? Maybe when she's kicking butt as Hermione; we might need to wait for the next phase of her career to see some real sex appeal, though!
Love Life: Although it's been on the down low, Emma is still evidently dating George Craig.
See her next: Duh! Harry Potter and the Deathly Hallows: Part 2! She's also starring in a Marilyn Monroe pic called My Week with Marilyn, along with Dominic Cooper, Michelle Williams as Monroe, and Kenneth Branagh as Laurence Olivier.
