Justin Bieber Was a Brat on ‘CSI,’ Star Marg Helgenberger Says

Justin Bieber made his acting debut on the popular cop drama “CSI,” as any respectable Belieber must already know by now. His character was shot to death earlier this year – and now, star Marg Helgenberger reveals working with him was not always a walk in the park.

Marg was doing an interview for the French radio show “Le Grand Direct des Médias” this Friday, when she was asked, among other things, what it was like to share the set with the biggest teen pop star of the moment.

“Um. Justin Bieber wasn’t bad,” Marg said, as the video below will confirm. Of course, interviewers couldn’t just let this slip and they pressed her for more details.

“He never acted before. I shouldn’t be saying this, but he was kind of a brat,” the actress revealed.

She explained that, while she didn’t get to spend too much time with Justin because of the roles they played, she personally had nothing to complain about his behavior.

“He was very nice to me. But he locked one of the producers in a closet and he put his fist through a cake that was on the craft service table,” Marg said.

This is not the first time that reports of Justin being a “brat” or even a “diva” come out online, though, it is the first time when one of the people working with him goes on the record with it.

In December last year, while in London, The Biebs threw a tantrum outside a restaurant, when his bodyguard interrupted his play with a remote-controlled helicopter and tried to lead him by the arm to the car, thus blocking paparazzi’s view of him.

Before that, in May that same year, a report said Bieber lashed out at a manager on a television show because he dared touch him lightly on the arm to show him the way he was supposed to go, as we also noted at the time.
