Showing fans a side of himself that they have never seen before, Justin Bieber flashed his rear end via his Instagram account on Saturday (January 19).

Sporting a black tank-top, camouflage cap, and aviator sunglasses, the 18-year-old pop star pulled down his undies while looking over his shoulder.

Though the shot was later deleted, the Biebs' manager Scooter Braun acknowledged the cheeky photo on his own Twitter page.

Making light of the pic, Scooter tweeted, "as a prankster u have to respect another good prank. only makes sense. #crackdealer." while Justin responded with "haha."
