Leighton Meester "Performs" at American Eagle Opening in Times Square

We knew Leighton Meester couldn’t sing. And now all of Manhattan knows it too!

The Gossip Girl delusionary performed a four-song set at the American Eagle store opening Tuesday night in Times Square, while castmates Sebastian Stan, Michelle Trachtenberg and Jessica Szohr cheered her on.

Cheered? Or laughed! Judging by Szohr’s face, we’re leaning towards the latter.

Also in the house were Pete Wentz on the turntable, Adrien Grenier and Adrienne Bailon.

Surely one of these people has the balls to tell Meester to quit while she’s ahead!
