Bieber bumped in onstage scuffle
Justin Bieber has had to halt a Dubai concert after an over-eager fan tried to rush the stage.
Mobile phone video released on the internet shows the male fan rushing towards the Canadian singer who was sitting at a piano on the edge of the stage.
Security guards tackled the young man from behind, spilling into the 19-year-old pop star and tipping over the piano.
Justin twisted away and then strolled off stage while the guards dragged away the fan.
The concert on Sunday - the second of a two-performance stand in Dubai - resumed after a short break and Justin appeared calm and unharmed.
He later tweeted: "Dubai. Nothing stops the show."
