Pop superstar and wannabe bad ass, Justin Bieber was reportedly involved in another nightclub brawl in South Korea... where he allegedly punched a DJ's manager in the face. But why is a 19-year old even hanging out at nightclubs?

The DJ, Michael Woods, isn't denying the rumors, via Hollyscoop:

“Story is [Justin Bieber] + his army of heavy security muscled in to the booth half way thru my set in S. Korea demanding hip hop,” Michael tweeted just hours after the altercation. “So when I told [Justin] to f*ck off and put some clothes on he took a cheap shot at my tour manager and fled behind a wall of security.”

Punching people over hip hop seems like a legitimate reason to sucker punch someone, doesn't it? If he continues down this road he's going to get caught without his security and it's not going to end well for the young entertainer.
