Emma Stone is one of our favorite gingers, but those red locks don't come naturally. Director Judd Apatow forced Emma to dye her hair for her role in Superbad in 2007, and she's been a feisty redhead ever since. That is, until she went back to blonde for her role in The Amazing Spider-Man. Of her change in hair color, Emma said, "I have blonde hair now since Gwen (Stacy) has blonde hair. My hair is naturally blonde, so it's kind of nice. I look in the mirror and say, 'Oh my God, it's me again, it's been so long!'"
