Carey Mulligan Goes Brunette, Debuts Dark Locks At NYFF

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.

See her new look below:
