Leighton Meester dressed up in sequins for an appearance on Late Night With Jimmy Fallon yesterday. The interview was just one stop in a long day of promoting her thriller, The Roommate, with Minka Kelly. Leighton and Minka started with a Q & A session at the SoHo Apple store before heading to a bash celebrating Leighton's Nylon cover later that night. Leighton may be busy with her big screen project, but she's still also focused on her role in Gossip Girl as the drama continues on the series.
