Last night Olivia Wilde stepped out with a brand-new chocolate brown hair hue, a big departure from the light blond strands she debuted back in April. The actress has been making drastic hair moves all year long. She kicked off 2012 by cutting her chest-length hair into a shoulder-grazing bob. Then came the honey-blond strands for her role in Rush, and recently she's been sporting something more in-between: an ombré style with chestnut roots. This isn't the first time we've seen Olivia go towards the darker end of the spectrum. What do you think of her latest look?
