In the old days, you could appear on a French talk show and gleefully unload some good set gossip without fear of reprisal, but now that we've got the Internet — and hordes of avenging Justin Bieber fans — we fear for Marg Helgenberger, who dissed Bieber's bullet-riddled CSI guest stint while overseas. (It's like the Dixie Chicks bashing Bush in London all over again!) At first, when asked to evaluate Bieber's acting acumen, Helgenberger was ... well, not generous, but not yet deliciously wicked: "Justin Bieber wasn't bad. He'd never acted before." Then, though, she let loose. "I shouldn't be saying this, but he was kind of a brat." Do continue! "I only had one small [scene with him] ... he was very nice to me, but he locked one of the producers in a closet. Yes, and he put his fist through a cake that was on the craft service table." And then he wished Laurence Fishburne into the cornfield — but it's good that he had a good time! Yeah, it's real good. (UPDATE: It's on! Tweeted Bieber just now: "it's kinda lame when someone you met briefly and never worked with comments on you. I will continue to wish them luck and be kind.")
