Dec 29 2009 Look what Britney Spears has gone and done again. No doubt we've seen the pop star switch up her hair color several times over the past few years. In fact, it was exactly six months ago that Britney went to the dark side, debuting chocolate brown locks, which didn't last all that long, as her signature blond mane returned by August. However, on a recent outing in LA, it looks as if Brit has busted out the hair dye once more, opting for this deep brown hue. While most of you said you preferred the Britney in her typical lighter-toned locks back then, now that we're in the heart of Winter, has your opinion changed?
