If you didn't think l'enfant terrible Justin Bieber was already bratty enough, we have new evidence that may finally convince you: Earlier this year, he was caught on video (by an apparently easily-impressed friend) peeing into a mop bucket in the back of a restaurant. Because, you know, class.
"Wait? Wait? What do you mean someone is upset they have to clean that? That's prime Justin Bieber urine," we imagine him asking incredulously when someone got angry.
