Justin Bieber may be 19-years-old, but clearly the little tyke hasn't been toilet trained yet as a video of him peeing into a bucket in a nightclub kitchen has been leaked (pun intended) on TMZ.
EEEEWWWWW.
Justin was making his way out of the club via the back entrance when he was caught short, but rather than hold it in or use the club's loo like a normal person, he whips out mini-Biebs and relieves himself into a cleaner's mop bucket.
And of course, one of Bieber's idiot mates reckons that he's got total 'swagger' for doing it.
What a bunch of chumps.
One of them can be heard saying: "We swagger man, that's the coolest spot to p*ss. You'll remember that forever," before shouting that they are the "f**king Wild Kidz" as they make their way out.
Oh, and if that wasn't enough, Justin then shouts "f**k Bill Clinton" as he sprays a picture of the former President with cleaning product as he leaves.
His mum must be so proud.
