Right on the heels of the premiere of her movie What Happens In Vegas... Cameron Diaz has once again gone from her signature bright blond locks to a more demure honey brown. Cameron isn't one of those stars afraid to experiment with her signature look. Yes, she is known for her bubbly, blond surfer-girl appeal, but the star definitely has gone through a series of styles through the years. Even in the past couple of years she has sported several different cuts and colors, including a dark, dark brown shade, which brought out her sparkling blue eyes. But now, as she promotes her movie, is this really the right time to change it up? And is this really Cameron's best color? Obviously, she would be gorgeous bald or with really bad hair -- hello, Being John Malkovich! But that doesn't mean go for it! What do you think of Cameron's choice?
