Known usually for her dark hair and major brooding on the red carpet and in editorials, Twilight star Kristen Stewart seems to have taken a lighter, brighter outlook on her celebrity status. In addition to the much-loved frocks she’s showcased on her Eclipse press tour, the 20-year-old showed up to a taping of The Late Show With David Letterman with shorter, red hair.

Pulled up in a sexy, messy hairstyle, do you like Kristen’s new look, or is she better off as a brunette?
