Justin Bieber has been reprimanded by his record company over his recent behaviour. The 'Baby' hitmaker was subjected to a 20-minute Skype chat with his US label bosses following his performance at The O2 arena in London on Monday, which saw him take to the stage two hours late. And the discussion also saw the 19-year-old singer warned to curb his partying ways and "stay in more". A source told the Daily Mirror newspaper: "Being amidst a barrage of abuse is uncharted territory for Justin. Understandably he is finding it hard to take ... His erratic behaviour and antics are not what his young fans expect of him. "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 ... Justin took the news well and has promised to go back to putting his fans first." After the talks, Justin's manager Scooter Braun advised the young pop star to stay "focused" on his Twitter account. He tweeted:"@justinbieber really good talk. #focused. (sic)"
