Marg Helgenberger Calls Justin Bieber a ‘Brat’
In a radio interview in France (via RadarOnline), Helgenberger let it slip that Bieber "was kind of a brat. 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 Bieber's acting skills, Helgenberger had this to say: "Justin Bieber wasn’t 'bad' bad ... But he'd never acted before ... He's better than you'd think."
