'CSI's' Marg Helgenberger: Justin Bieber 'kind of a brat'

Justin Bieber, "un sale gosse" chez Les Experts by Europe1fr

In a recent radio interview that was filmed before a live audience, "CSI" star Marg Helgenberger was asked about Justin Bieber's recent guest-starring appearances. She defended his acting, but said he wasn't the easiest person to work with.

"Justin Bieber wasn't bad. He'd never acted before ... He's actually better than you think," says Helgenberger, about his acting abilities.

"I mean, I suppose I shouldn't be saying this, but he was kind of a brat," she laughs. "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 services table."

So a 17-year-old boy with unimaginable fame and fortune is a bit of a brat? We are shocked (SHOCKED!) to find that gambling is going on in here!

Marg also says she will be back on "CSI" for Season 12, but for a limited number of episodes. And she says of losing star William Petersen, "Obviously, when he left there was a bit of a loss because he was such a character that was so beloved by so many people. But Laurence Fishburne is an excellent actor and a really wonderful person."
