Justin Bieber has sweat dripping down his face while leaving the Ten Goose Boxing studio on Saturday morning (December 3) in Van Nuys, Calif.
After being spotted at the same gym the day before, it seems that the 22-year-old singer has taken up boxing as his new workout passion!
During the workout the day before, Justin was spotted going shirtless in the ring. See those pics in the gallery.
The night before, Justin hit the stage for a performance at Jingle Ball in Los Angeles.
