JUSTIN BIEBER had a scare onstage in Dubai on Sunday (05May13) when a fan grabbed him from behind and then knocked over his piano.
Cell phone footage of the incident shows security guards dashing onstage to re-set the piano, which fell apart as the stage invader ran into it in an attempt to avoid the minders and crew.
One fan tells newspaper the National that the Baby singer was at the piano when the alleged attacker, described as "a youth in a white shirt and jeans," rushed onstage.
The incident was dealt with quickly and Bieber reportedly carried on with the show as if nothing had happened.
It hasn't been the greatest weekend for the teen star in the Middle East - on Saturday (04May13) he upset fans at another Dubai gig when he reportedly hit the stage two hours late.
Many parents complained about their children being kept awake until the early hours since Sunday is a school day in the United Arab Emirates city, according to local paper al Arabiya.
Bieber's late arrival comes just weeks after he kept fans waiting for two hours at London's O2 Arena in March (13) as part of his current drama-dogged Believe world trek.
