He once cupped a fan's boob for all to see--while he was dating Selena Gomez!

He's sometimes too lazy to walk and needs to be carried.

There's photographic proof he's mooned the unsuspecting paparazzi. Crack kills.

Justin Bieber's prostitute crossed him when she secretly took a picture of him sleeping in her bed. Oops!

He once peed in a mop bucket THEN said not so nice things about Bill Clinton.

Let's all take a minute to feel bad for the monkey that has to witness this.

He also "snuck" out of a brothel (too bad his bodyguards didn't).

He wore a gas mask in order to make himself more, I mean less, conspicuous?

And finally, when he stepped on the carpet you are NOT suppose to step on.
