Justin Bieber Performs on the Jingle Ball Circuit…Shirtless (Video)

If you thought girls screamed loudly for Justin Bieber, wait until he takes his shirt off.

The 18-year-old had a busy week playing numerous annual Jingle Ball shows for radio stations from Los Angeles to Boston to New York to Tampa and everywhere in between.

Justin lit up the stage with his hits like “Beauty & A Beat” and “Boyfriend” and for some of the shows he brought back his holiday single “Mistletoe.” In both Boston & New York City for KISS 108 & Z100, the Biebs decided to give the girls an early Chrismtas present when he went shirtless for his performance of “Baby.”
