Bieber called a `brat` by CSI co-star
Los Angeles: Teen pop sensation Justin Bieber behaved like a "brat" on the sets of TV series `CSI`, according to his co-star Marg Helgenberger.
The Emmy-winning actress has angered Bieber fans by suggesting the 17-year-old was difficult while he filmed a cameo on the hit crime show, reported Us magazine.
Helgenberger, 52, said during an interview with a French radio station, "Justin Bieber wasn`t bad. He had never acted before. I shouldn`t be saying this, but he`s kind of a brat."
Bieber made his acting debut alongside Helgenberger in an episode of `CSI: Crime Scene Investigation` last year.
"He was very nice to me, but he locked one of the producers in a closet," she said, adding that he also "put his fist through a cake that was on the food service table".
When asked about the `Baby` hitmaker`s acting skills, Helgenberger said, "I am pretty open to whoever comes on the show. If someone is a jerk, that bothers me. If they`re a so-so actor, it doesn`t bother me. [Bieber] is actually better than you`d think!"
