Natural hair color: Blonde

Why she went red: She dyed her hair for a high school play and never looked back. "I was quiet and reserved as a blonde," she told "But it’s like the red hair immediately unleashed this fiery personality I had inside."

Still, the fact wasn't front-and-center when she won the Miss USA 2011 contest. Many of her newly-minted fans were disappointed to find that her signature locks were dyed, but (let's face it) hotness trumps all, and she was forgiven.
