Selena Gomez

Yes, Selena Gomez is a former Disney Channel star, and we all know how those can turn out. And, yes, she's tween idol royalty, thanks to her current status as Justin Bieber's girlfriend. But you can't hold Gomez's relationship with the Biebs against her; everyone makes mistakes when they're young. This rising star is more than cute and ambitious enough to make up for her questionable taste in men. Every girl between the ages of 10 and 16 wants Gomez out of the picture (and some of their moms, too), and we'd be more than happy to steal her away from the current prince of pop.

 

  Mila Kunis

 

After her 2010 make-out with Natalie Portman in Black Swan, last year's Top 99 runner-up defied all logic by kicking things up a notch in 2011. Mila Kunis extolled the virtues of casual sex (albeit with Justin Timberlake), dressed down a confrontational reporter in fluent Russian and made one lucky Marine's year. Proving she has the personality to match her looks, the down-to-earth actress even more after accepted a YouTube invitation to a Marine Corps Ball. Forget friends with benefits -- that's marriage material right there.
