Audrina Patridge lightened up her long, layered brunet locks with ombré blond highlights this week. The California girl and Bongo spokesperson has switched from dark brown to sunny blond to a brown-golden mix quite a few times since being in the spotlight, and this shade is actually closer to her natural hue. "Now that I'm not filming, I have fun with my hair!" she told us at the Badgley Mischka show during New York Fashion Week earlier this month.
