London, March 7 (IANS): Singer Justin Bieber has reportedly been warned by record label Universal's bosses to make fans his priority and keep a check on his party habits.

Bieber faced bad publicity when he turned up three hours late for a gig here, which is part of his ongoing "All Around The World tour".

He was booed by fans, who expected him to hit the stage at the O2 Arena at 8.30 p.m. However, the label bosses sent him a warning after calling an emergency meeting via Skype, reports mirror.co.uk.

"He is a huge cash cow for the label and of course, they're desperate to keep both him and the fans sweet. His erratic behaviour and antics are not what his impressionable young fans expect of him," a source said.

"After an emergency meeting in the US, Justin's people had him on Skype to bosses and he was given a serious talking-to. It was suggested he start staying in more and basically cleaning up his act," the source added.

The teen sensation has also been suggested to stay more indoors when in Europe.

"He's kicking off the European leg of his tour next week and has been told to stay in more when he's not performing. Justin took the news well and has promised to go back to putting his fans first," a source said.
