Rihanna

Profession: Singer
Age 23

Yeah, she's not a natural redhead, and neither are a lot of the hotties on this list, but damn, RiRi has killed the color just as well as anyone. Short, long, it doesn't matter. Like every one of her eye-catching hairstyles, it was gone after one album cycle, but we'll never forget that moment when the Bajan beauty went ginger.
