Leighton MeesterLeighton Meester debuted a brand new look during her performance at Troubadour in West Hollywood last night.

The actress turned singer is sporting new bangs and has said goodbye to her sun-kissed highlights, taking a giant step away from her 'Gossip Girl' look. The singing side of the 25-year-old seems to have a much more Bohemian style than the snooty Blair Waldorf. Meester went for a much more casual look with her wispy new 'do, wearing a long white skirt and and casual T-shirt as she performed songs from her new album in front of a crowd, which included her father and 'Gossip Girl' co-star Michelle Trachtenberg.

Meester isn't the only actress to change her look while she isn't taping. 'Glee' star Dianna Agron chopped off her blonde locks as their season wrapped, showing off a fun messy bob, just in time for summer.
