Taylor's in Disguise For a GG Halloween With Ed and Leighton

Taylor Momsen wore a Halloween costume for Gossip Girl in NYC yesterday, while Ed Westwick and Leighton Meester were decked out in their usual outfits. Get in the mood for the ghoulish day on Oct. 31 by taking my themed quizzes, and playing my faceoff game about who's the scarier villain! The GG cast have been spotted fliming scenes in several fancy costumes, and Leighton was all over New York Fashion Week in various fab outfits. Ed's now back on the East Coast after shooting his short film in London, while Taylor's been sticking to Manhattan whether she's on set or promoting Madonna's clothing line.
