Justin Bieber explains emotional performance at VMAs.

Justin Bieber during a chat show appearance on Wednesday night insisted his emotional performance at the MTV VMAs was 'authentic'.



The 21-year-old Canadian pop star broke down in tears on Sunday after performing his new song What Do You Mean.

'It was so overwhelming,' Bieber said of his performance while chatting with host Jimmy Fallon on The Tonight Show.

'I missed some cues so I was a bit disappointed about that. But just the support. ...I didn’t expect them to support me in the way they did. Last time I was at an awards show, I was booed,' the singer said.

He explained that he has been working hard on his new album and the 'man I want to become'.

'What was so special about the emotional moment at the end was that it was real. It was authentic. I just wanted it so bad,' Bieber said.
