CSI actress says Justin Bieber is a brat

A CSI cast member has branded Justin Bieber a brat.

CSI: Crime Scene Investigation actress Marg Helgenberger dished the details on J-Biebs behaviour.

“I shouldn’t be saying this but he was kind of a brat,” Marg said, reports ShowbizSpy.

“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 cast’s table.”

Marg did have some positive comments though.

“Justin Bieber wasn’t bad,” she said. “He’d never acted before … He’s better than you’d think.”
