Justin Bieber rolled into the exclusive 1OAK club in Los Angeles last night and gave an impromptu mini-concert for the surprised and turnt Southern Californian crowd. The Canadian pop star busted out a performance of his hit song "What Do You Mean?" and later brought up rapper Tyga to the stage for a bit. "How many people thought you would like Justin Bieber?" the singer asked the largely adult crowd before hitting them with some more tunes. From the sound of the cheering, it's hard to imagine that anyone in the room wasn't down with the Biebs that night.
Check out a few clips from Bieber's 1OAK performance below.
