Justin Bieber gilded his resume this year with a why-the-heck-not guest arc on CSI, which culminated in a bloody bullet ballet that was like Bonnie & Clyde except with better hair. At least one CSI cast member wasn’t too impressed by the tweenybopping idol, though; when Marg Helgenberger was speaking to French radio last week, she said, “I shouldn’t be saying this, but he was kind of a brat.” Wearing an impish grin that positively screamed I would never say this on American radio, Helgenberger noted that the star was perfectly nice to her but, “He locked one of the producers in a closet…[and] he put his fist through a cake that was on a craft services table.”

Kids these days, with their closet pranks and pastry-punching! What’s happening to America? Let’s have a serious discussion about it on French radio. UPDATE: Bieber has apparently responded to Helgenger’s comments via his Twitter page, saying “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.” He later added, “I know who i am and sometimes people r just going 2 say what they want. Keep ur head up and be the man ur mama raised. #killemwithkindness,” before ultimately concluding, “dont spread gossip and dont spread rumors about others…im a kid and i know that. #respect.” In conclusion, Hollywood is exactly like fifth grade, except apparently with more cake.
