Justin Bieber was not greeted with happy shouting when he entered the stage during last night's London concert.The crowd was furious and even booed at him on stage - because he was over an hour and a half late for the show. "'The fans were infuriated and they were booing on a number of occasions before he finally turned up on stage.", a source claims. He never mentioned why it took him so long to get going, but the audience forgave him pretty fast when he finally started singing. Is he becoming kind of a diva? (contactmusic)
