Justin Bieber shows off his "stache"

JUSTIN Bieber released a teaser for his upcoming documentary Believe this weekend - trouble was, no one was talking about the documentary.

What everyone WAS talking about was the Biebs' poor excuse for a moustache.

"That's how much of a man I am," he said, pointing to the wispy covering of hair on his upper lip, "stache".

Added Usher, out of nowhere: "As a 19-year-old, Justin is now becoming his own man."

Added his mother, Patti: "I think it's hard for parents to let go, but it's really exciting too, to see him maturing."

The 36 second clip ends with the tagline: "There's more to his story".

Hopefully NOT the story about how Bieber got his 'stache. Nobody wants to see that.

Believe, is the follow-up movie to his Never Say Never concert film, which raked in a whopping $98m from a budget of just $13m.

Meanwhile, Bieber got himself into trouble in a DJ booth in South Korea on Friday night after a DJ refused to play his request.

DJ Michael Woods accused Bieber of taking a "cheap shot" at his tour manager, before running away.

In an angry Facebook post the English DJ said: "Right, the story is Justin Bieber and his army of heavy security muscled in to the booth half way through my set in S. Korea demanding hip hop.

"So when I told him to f--- off and put some clothes on he took a cheap shot at my tour manager and instantly fled behind a wall of even more of his security.

"Next time u wanna take a cheap shot at my Tour Manager @justinbieber make sure u stick around to follow it through instead of runnin off like a lil p----."

There's no word on whether he was sporting the 'stache or not.
