Justin Bieber caught some people in the gym by surprise when he popped up to get some run at an open gym. He hit the hardwood at Equinox in West L.A. for a pickup game with his friends and you knew people were gonna sneak some clips of Biebs doing his thing on the court. The video isn’t that long so you can’t tell if he is any good, but this isn’t the first time he has been spotted working on his game. Hit the jump.
