Who says blondes have more fun? Carey Mulligan ditched her signature blonde 'do and has gone to the dark side! The actress showed off her new brunette in New York over the weekend. Carey rocked a cut-out black dress with a bejeweled collar, but all eyes were on her gorgeous brown locks! It has been awhile since we have seen Carey with dark hair and we forgot how great it looks.
