Justin Bieber Shows Off his Sexy Ass Butt!

Justin Bieber’s been caught with his pants down—and on purpose! yup — he’s showing his butt.

Justin posted a revealing photo of himself, his backside, via his Instagram Saturday. He later deleted the shot, but according to his manager Scooter Braun it was all in good fun.

Scooter tweeted: “as a prankster u have to respect another good prank. only makes sense. #crackdealer.” To which he responded with a simple: “haha.”
