Baby Biebs sang his little heart out at last night’s sold out Z100’s Jingle Ball at Madison Square Garden.
Our fave 15-year-old started with “Love Me,” then continued the night with “One Less Lonely Girl,” in which he serenaded one lucky fangirl onstage with a bouquet of red roses.
John Mayer even recognizes the power of the Biebs. “I’m John Mayer, I’m 52 years old,” he said after he performed. “Get the old dude off the stage and get Justin Bieber on here!”
