Candace Bailey

If your crush on Candace Bailey seems older than her age would suggest it should be, that's because this personable and adorable TV personality worked into your brain back in your Nickelodeon-watching days. Teen actress turned sexy-geek co-host of G4's Attack of the Show!, Bailey seems like "the girl with all guy friends" wrapped in a supermodel exterior. Even when modeling in her underwear for sexy photo spreads in men's magazine, her posing still seems tongue-in-cheek, which just makes her all the more endearing.

 

  Jennifer Lawrence

This 21-year-old actress has accomplished two major feats: She made a backwoods hillbilly in Winter's Bone and a blue mutant in X-Men: First Class both appear sexy. That alone should have won her an Oscar for Best Actress. Seemingly overnight, Jennifer Lawrence went from gawky teen to goddess after knocking around Hollywood for most of her childhood. This year, we'll get to see her toughen up as the lead in The Hunger Games and see how she handles the pressure of insane teen fandom. Congrats, Jennifer, you're the new Kristen Stewart.
