For most of her years in the spotlight, Britney Spears has been a blonde. But this weekend, she showed off a new brown hue while strolling around in Los Angeles. It isn't the first time that Brit's been a brunette, but it's been at least a year since we've seen this rich chocolate color on her. Some might prefer her with flaxen hair, but I say, never underestimate the power of the dark side. Which hair color do you think flatters her more?
