Leighton Meester not only has mastered the role of Blair Waldorf the Upper East side snob on Gossip Girl, but Leighton has now mastered the art of singing as the female vocalist in Cobra Starship's new song 'Good Girls Go Bad'. Leighton plays the good girl with the tough image, running an underground speakeasy bar in the music video for 'Good Girls Go Bad'.

According to MTV: The concept of the video is that Meester runs an underground speakeasy, complete with shelves of booze, gambling tables and a dance floor. The band is in charge of the above-ground deli that acts as a front operation to hide the debauchery within. To gain access to the illegal club, patrons must order the correct sandwich and proceed down a staircase.

"Well I can tell you what the most unrealistic thing is about Gossip Girl --- going to Brooklyn is NOT like walking across the street for a cup of coffee. And Rich people NEVER go to Brooklyn ... "  - Gabe Saporta -
