"Hairdid." That's how Lily Allen [aka Lily Cooper] announced her new look on Twitter and Instagram Wednesday, sharing this photo of her newly darkened locks and sleek bob cut. She later added a selfie from the salon, mid-process, along with the tag, "back to black," a reference to her formerly auburn hair -- and one of her old friends, the late, great Amy Winehouse. Lily quit music in 2009 to get married and start a family (she and husband Sam Cooper have two daughters). She's currently working on her first studio album since "It's Not Me, It's You."
