Is it life imitating art? Leighton Meester attended a party in her honor at New York’s W Hotel — and all the cool kids showed up! The party was thrown by Nylon Mag, whose cover Leighton graces this month. Gossip Girl stars Jessica Szohr and Michelle Trachtenberg were there along with Leighton’s The Roommate co-star, Minka Kelly. Bonus: Kanye West and Jared Leto showed up just in time to flip off the camera. Thanks, guys!
