Justin Bieber Works Out With Mike Posner Before Believe Concert

January 26, 2013 • By

Justin Bieber Mike Posner Gym

Justin Bieber invited Mike Posner to perform at his Believe Concert this week, and before the show the duo worked out together. Alfredo Flores shared the photo above of the group at the gym.

Have you heard the recent drama that Justin encountered at a gym in North Carolina? He was working out at the same time as a radio DJ and according to the DJ Justin was mocking her during her workout routine. Yikes!

Justin also had to deal with some disrespectful fans this week – what a bummer!
