The 17-year-old singer played a troubled teen in a multi-episode guest appearance on "CSI" this past winter and he must have been doing method acting -- because he was "a brat," reveals the CBS show's star Marg Helgenberger.

"I probably shouldn't say this, but he was kind of a brat," the actress said in an interview with French radio show Le Grand Direct des Medias on Friday.

Although Helgenberger said he was nice to her in the one scene they shared, he didn't have the same love for some of the crew.

"He locked one of the producers in a closet," she added. "And he put his fist through a cake that was on the craft services table."

LOL I was about to post this.

She really doesnt know what she's in for

Does she have a twitter?

"He locked one of the producers in a closet,

There you go girl. Now you're officially dead. Bai!

I love this kid, but he needs to stop allowing his fun side to interfere with his professionalism and career.

He's just a kid, he was probably just trying to have a little fun. But there is a line between playing and being professional and he's probably still learning that...



Did I just defend Bieber, oh no...

He's 17, and if he's going to be getting into this industry then he should be more professional. Boy should be grateful.

He's 17 not 9. Putting a fist through a cake is not something I ever thought of doing, I was pretty mature at that age.

PLEASEEEEEEEEEE He's not a kid anymore he's ****ing 17 i was starting my university at 17

She better shut that punk down. I expect Selena to write a tiny break-up song once they split apart.

Wasn't he like 15 or nearly turned 16 when he filmed his episodes?

Like I said there is a line between having fun and being professional and he's still learning it. Yes he is 17, newly turned, but I know 17 year olds that still act that way and it drives me nuts. Every man and women mature differently from one and another. He's probably just one of those guys that'll probably never be mature until he learns from his mistakes he makes like being arrested multiple times, and don't deny it we all see it happening

Okay enough trying to defend him, your comments have been slaps... I just hope Marg is in for a rude awakening if she has a twitter cause his fans are going to go psycho on her

He locked a producer in the closet, Justin needs to come out of the closet before he starts locking producers in there

That was witty and totally not cliche or predictable or anything.

But people mature differently.

She better have some security... her personal safety is at stake now.

Not to that great an extent. No 16/17 year old I know would do that, and definitely not at a job. Hell, even a 14 or 15 year old would prolly know that.

That's true, but he might not have been thinking?
