We finally watched Cobra Starship's music video for their new song "Good Girls Go Bad," which not only features Leighton Meester's acting skills, but also her singing chops. We've know for a while now that Leighton can sing, though she does tend to do that weird West Coast accent/drawl thing with her voice in this song, kind of like Ashlee Simpson if the latter had a decent range. Leighton looks lovely in the video, of course, but our favorite things are the obvious nods to Gossip Girl, beyond even the basic premise and title. Can you spot them?
