Justin Bieber has posted a very cheeky snap on Instagram today (20 January), before swiftly deleting it before he got in too much trouble!
The picture shows Justin with his back to the camera, a faint smile just visible on his lips and he pulls down his pants and exposes his bare butt!
The picture was captioned simply with “#moon” and was promptly deleted from the site – but not before it could be screen shotted and spread around the world!
Justin then seemingly responded to the furore the picture created, by posting “haha” on his Twitter account.
Despite the seemingly innocent nature of the prank, some are suggesting that instead of an adolescent prank – Justin’s cheeky reveal is actually aimed at ex-girlfriend Selena Gomez!
She had her own derriere featured in another kind of picture – a promotional poster for upcoming flick Spring Breakers!
So what do you think? Was Justin’s butt pic just a prank? Or directed at Selena?
