She may be a “Gossip Girl” by day, but Leighton Meester took on the role of pop star on Tuesday night when she performed at the opening bash for the American Eagle Outfitters store in Times Square. In front of an audience that included “Gossip Girl” castmates Jessica Szohr and Michelle Trachtenberg, the actress bopped around the stage in a black bandeau bra and belted out several singles from her upcoming solo album, slated to hit shelves early next year. Among them were “Somebody to Love” and the not-so-subtly-titled ditty “You’re Not as Cool as You Think You Are.” “This song is dedicated to someone I wish it wasn’t dedicated to,” Meester told the crowd. “This guy is called a douche bag….This douche bag’s name is Rick.”

Today, American Eagle Outfitters’ chief executive officer Jim O’Donnell joins Dennis Walcott and Jeanne Mullgrav for the grand opening, which includes a Mayoral proclamation declaring Nov. 19 “American Eagle Outfitters Day” in New York City, which was projected onto the LED signage outside the store as well.
