Justin Bieber reportedly 'threw a strop' before his late performance in London Monday night.
The 19-year-old pop star was scheduled to start his set at The O2 arena at 8.30pm yesterday, but didn't hit the stage until almost two hours later.
Justin's tardiness infuriated young fans and their parents in attendance, as many children had to leave before the show was over to be on time at school the next morning.
Although Justin blamed the delay on technical difficulties, insiders claim that an attitude problem was the cause.
'His lateness was because he didn't get out of bed until late and sat in his dressing room playing games - even though his door was being knocked,' a source told British newspaper The Sun.
'He then threw a strop as he said he wanted a shower first, despite already being late.
'Justin arrived at the O2 at 3pm to do some meet and greets, but he didn't get up until late because he'd had a heavy night at his hotel.'
Mother Lindsay Gilbertson's daughter was at the show and the matriarch also heard rumours that Justin was being bratty before his performance.
'We were told he was kicking up a real fuss,' she said.
'He was saying, 'It's my show, I'll go out when I want to'.'
A staff member working at the concert claims the teen icon was irascible.
Apparently Justin made the environment unbearable for those backstage.
'He was arguing with members of his management, his family. It was a really uncomfortable atmosphere,' the employee revealed.
'His attitude was, 'I'm the star and I can do what I want'.'
The young heartthrob has hit headlines recently for a number of controversial reasons, including his alleged use of marijuana.
Justin insists last night's scheduling issues were blown out of proportion.
'my relationship with the media is not always easy but im trying. Im all about the music and the performance and i respect my fans,' he wrote on Twitter.
'i never have any intent to upset or let anyone down. and Im not okay with things being exaggerated. once again sorry for anyone upset.(sic)'
