FILE - In this Sept. 30, 2012 file photo, Justin Bieber performs at the MGM Grand Garden Arena in Las Vegas. Bieber is known for his slick dance moves onstage. But spinning away from a mash-up between security guards and a rogue fan has become the hit of his concert Sunday, May 5, 2013, in Dubai. Mobile phone video popped up across the Web on Monday showing a male fan rushing toward the 19-year-old performer, who was sitting at a piano on the edge of the stage. Security guards tackled the young man from behind, spilling into Bieber and tipping over the piano. Bieber twisted away and then strolled offstage while the guards dragged away the fan.
