Justin Bieber's manager has dismissed claims that the singer annoyed producers whilst on the set of CSI: Crime Scene Investigation.

The teen star has appeared in a couple of episodes of the popular crime TV series, but his manager Scooter Braun told Rolling Stone that a producer for the show complained about Bieber's alleged unprofessionalism.

Braun added that he reckons the CSI team lost sight of the fact that Bieber was a teenager and overreacted as a result. He said:

"The producer gets on (the phone) - he's a stuffy dude, and he's like, 'Justin is incredibly unprofessional. He put his hand in a cake, he locked me in a closet...' I said, 'Let me ask you a question. When he locked you in the closet, did you tell him you were angry?' He goes, 'No, I needed him to work, so I laughed.' And I said, 'So he saw you acknowledge his joke and say it's OK? Then you're more to blame than him. He's a kid - he's waiting for someone to tell him where the limits are'."

Braun concluded: "At the end of the day, even in his most selfish moments you just need to point out that he's being selfish. He's more embarrassed about it than anything. When he's being a p**ck, he's not being a p**ck because he's famous. He's being a p**ck because he's a kid."
