The latest in entertainment news is, after finding out about how Marg said he was a “brat” on set, Justin took to Twitter and fired back at the actress (without actually mentioning her name):

“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.”

Marg had earlier claimed on a radio show that Justin was “kind of a brat” when he guest starred on CSI previously. Justin, of course, did not take this well. However, we have to give props to the Biebs—he handled it like an adult:

“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. “

Good for you, Justin! Don’t you think he acted more maturely than Marg did?

According to Hollywood news and gossip, Marg was interviewed in a French radio show saying Justin’s a truly good actor(of his scenes at CSI), seeing as he’s never acted before. But the gorgeous 52-year-old actress also had this to say about The Bieb:

“..he 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.”

And what were you like at 17, Marg? We wonder…

Just for kicks here’s Justin‘s pivotal scene on CSI. I bet Marg really loves this one:

William Petersen, the head dude on CSI (the Las Vegas version) is leaving.  His character will somehow fade out mid-season of this year!  He did not want to renew his contract and wanted to have more choices and options open to him and his acting future. 

There goes the show!  Once the big name stars exit, it usually goes down the tubes from there.  ER is the exception, only because they didn’t know to quit years ago when they should have.  Will you still watch the show with him gone?  How will he leave?  I think he will go off to follow Sara (Jorja Fox) who left last season.
