A representative for Mac Miller has dismissed concerns for his health after the rapper appeared to collapse midway through a concert in Phoenix, Arizona on Friday (09Aug13), insisting the drama was all part of the show.

The hip-hop star was playing the title track from his latest album, Watching Movies with the Sound Off, for fans at the Celebrity Theatre as part of his The Space Migration tour, when he fell to the ground.

Video footage of the incident shows members of his live band briefly halting the music to check on Miller, who was hunched over on his knees, before jumping back to his feet to continue with the performance.

The clip caused a stir as it emerged online on Monday (12Aug13), but Miller's spokesperson has brushed off the stage fall and is adamant it was intentional.

A statement issued to HipHopDx.com reads: "He didn't collapse. He just ducked down on stage as part of the set."

Miller has yet to comment on the incident himself.
