Lady Gaga  -Gossip Girl - red dressGiovanni Rufino/The CW (2)

Tonight in a much-anticipated guest appearance, Lady Gaga invades Gossip Girl‘s Upper East Side in none other than a 30-foot-long dress and nipple pasties. Thanks to the wheeling and dealing of Blair Waldorf, Gaga performs her hit song “Bad Romance” as part of a private show, and we can’t wait to see what other tricks she has up her sleeve! Check out a preview of her performance and watch Gossip Girl at 9pm EST tonight on the CW for the sure-to-be epic episode!
