DUBAI, United Arab Emirates » Megastar singer Justin 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 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.

The concert Sunday — the second of a two-performance stand in Dubai — resumed after a short break and Bieberappeared calm and unharmed.

He later tweeted: “Dubai. Nothing stops the show.”
