Justin Bieber Moons Twitter, Manager Thinks Its Hilarious [NSFW Photo]

Justin Bieber is set to pass Lady Gaga as the most followed celebrity on Twitter, and apparently chose to celebrate by mooning the lot of us.

The Biebs flaunted his backside on Instagram, sporting a black tank-top, camouflage hat, aviator sunglasses, and little else as he pulled down his undies and snarked over his shoulder at us.

The butt-shot was quickly deleted by Bieber. Even though hes the second biggest celebrity on Twitter, The Biebs somehow failed to remember the first rule of the Internet. Many celebrity blogs picked up the image in one form or another, making Biebers derriere both immortal and legend.

GossipCenter has a pretty good SFW picture of Bieber mooning Twitter, but the crown in the NSFW competition goes to The Huffington Post, who managed to get a big, blown-up picture of Biebers un-adulterated butt crack (which we have posted below for your enjoyment).

Bieber has exposed himself on social media before, having posted a picture of his six-pack ab! s in November, days after his breakup from Selena Gomez. He said that he had been trying to get into better shape.

Ive been working out in the gym, getting bigger, Bieber said at the time, trying to get sexy for the ladies.

Biebers back-side is making rounds on social media right now, with the best reaction coming from his own manager, Scooter Braun, on Twitter. Braun wrote:
