Justin Bieber late for Dubai gig

Teen star Justin Bieber enraged fans once again on Saturday (04May13) when he turned up two hours late for a concert in Dubai.

The Baby hitmaker had been expected to take to the stage at the Sevens Stadium at 8pm (local time), but it was only at around 10pm that concert officials announced the star was "on his way", prompting him to be booed by his young devotees.

Many parents have since 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 Believe world trek.
