Who knew Bieber Fever could be deadly?
Filming his role as a troubled teen for CSI: Crime Scene Investigation
, Justin Bieber
came face-to-face with a fake corpse on set of the CBS show. Hovering over the prop, the pop star, 16, got into character and gave the camera his best look of horror.
"He did a really good job," CSI
's executive producer Carol Mendelsohn tells USA Today
In his acting debut, Bieber plays Jason McCann, a troubled teen in a dysfunctional, anti-government family. He has a foster dad in prison and a brother bent on revenge against the police. So where does that leave Bieber's character? "Is he a good kid stuck in a bad situation or is he a bad kid hiding behind the cutes?" Mendelsohn says. "He's caught in the middle."
Bieber was excited about his stint on the show and took to Twitter
to tease the episode for fans. "Amazing day ... excited for you guys to get to watch it ... and yes I did prank the EP of the show ... somebody got locked in the closet," he Tweeted after shooting the episode. "Thanks to everyone at CSI for having me."
Bieber will be back on the CSI
set early next year to film a second episode, due in February, that will continue his character's storyline. The first episode airs on Sept. 23. --Alison Schwartz
