Justin Bieber was recently shot dead on CSI (watch below!), and now the show is coming back to haunt him. In a recent interview, actress Marg Helgenberger said of the former guest star: "Justin Bieber wasn't bad. He'd never acted before. I shouldn't be saying this, but he was kind of a brat. I only had one small [scene with him]... 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 service table." This isn't the first time he's been called a brat, either—last year BBC Radio 1 DJ Scott Mills called him "a precocious little brat.”

The Biebs has already responded to the latest over on Twitter, 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... don't spread gossip and don't spread rumors about others... I'm a kid and I know that."

Thankfully, Bieber is fully armed to protect his public image with two recent PSAs (for PETA and for the Long Island mall riot of 2009—never forget). However, the press is also armed, with proof that this 17-year-old boy may just be a "brat" after all. E! Online has pointed out what they deem "a disturbing pattern" in Bieber's behavior. You know, like that time he used profanity, or threw a water balloon! Our prediction: this will all end after the pop star grows up and isn't a teenager anymore.
