All sorts of new talent popped up this year -- some of it from YouTube, some from Oscar-nominated films and well, the rest of it straight from Jersey Shore!
2010 was the year that Justin Bieber and Ke$ha dominated the music charts, but Will and Jada's daughter Willow Smith stepped onto the scene with a bang this fall, and the 10-year-old has won us over with her catchy tunes and wacky sense of style.
As far as TV and film go, Easy A star Emma Stone broke out of her shell this year (and she just debuted a hot blonde 'do), and the cast of Jersey Shore managed to make Barbara Walters' Ten Most Fascinating People list, so clearly they're still doing something right! So who's left? After playing a ballsy American soldier in The Hurt Locker last year, Jeremy Renner has worked his way up the ladder and he's now set to take over the Mission Impossible franchise, so it looks like we have a Tom Cruise in training! But who's YOUR pick?
