One person who doesn't have Bieber Fever? Actress Marg Helgenberger, who says the teen idol behaved like a "brat" during his guest stint on "CSI: Crime Scene Investigation."
During a recent radio interview with Europe 1, Helgenberger was asked what it was like working with Bieber, who played bad boy Jason McCann in two episodes of the popular CBS series.
“I shouldn't be saying this, but he was kind of a brat," she said. "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."
As for whether Bieber was a good actor, Helgenberger replied diplomatically, "Justin Bieber wasn't bad. But he'd never acted before… He's better than you'd think.”
