5. EMMA STONE
Having recently gone blonde for her role in the now-in-production The Amazing Spider-Man, Stone returned with the red hair we fell in love with in Easy A, for which the hot actress won "Best Comedic Performance." But is it really a performance when it's so completely believable? What geek wouldn't beg, and pay, Stone to just pretend they got to second base? We would, and we're not even geeks.
