Rapper starts brawl at performance

US rapper K-Mac has allegedly sparked a brawl at one of his Melbourne shows.

Kevin McCall taunted fans, who then stormed the stage at his performance in Hawthorn in the early hours of Sunday morning.

He was heard saying: "I think I hear some boo-ing. I'm a real east-side [beep] so if you're boo-ing come up to the stage."

The highly promoted performance was reduced to a 20 minute cameo, leaving fans disappointed and out of pocket.
