Blonde no more!
Carey Mulligan debuted new brunette locks while attending the premiere of "Inside Llewyn Davis" at the NY Film Festival on Saturday (Sept. 28). The 28-year-old actress, who has been sporting a cropped blond 'do for a while, walked the red carpet in a sexy black dress, which bared her toned midriff.
Mulligan's man Marcus Mumford of Mumford and Sons also attended the screening, looking dapper in dark jeans and a suit jacket.
No word yet on whether Mulligan's dye job was a personal or professional choice -- but we're loving it.
