Selena Gomez arrived in NYC last night, fresh from a stay in Atlanta, to perform "Love You Like a Love Song" this morning in Central Park — check out photos from Selena's recent video shoot for the track! The concert was broadcast on Good Morning America, and Selena was thrilled to sing as she's recently found out that her new single, "Who Says," has gone platinum! Selena also talked to the show's hosts Robin Roberts and George Stephanopoulos about possibly working with her boyfriend, Justin Bieber. Selena said of a Justin collaboration, "Whenever I do songs, I kind of do them organically, so if it happens, it happens." She was off to celebrate not with Justin, but with her Monte Carlo costars Leighton Meester and Cory Monteith. He was in the Big Apple area on tour, having taken the stage in New Jersey last night with his Glee cast mates and Gwyneth Paltrow.
