Carey Mulligan is back to brunette mode.
The 28-year-old Great Gatsby star stepped on the carpet of the premiere of Inside Llewyn Davis Saturday ditching her blonde locks for a new brunette hair hue.
Mulligan, who had been rocking short blond locks as of late, attended the screening with her Mumford and Sons hubby Marcus Mumford, wearing a chic, bejeweled black halter dress that showed off her midriff.
The actress stars in the Coen brothers film, which centers on a week in the life of a young singer Llewyn Davis (Oscar Isaac) as he navigates through the Greenwich folk scene in 1961.
