As J-14 previously reported, Justin Bieber will guest star in the season premiere of CSI, airing September 23. He already started taping his reoccurring role of "troubled teen" Jason McCann and Tweeted along with the photo of him in handcuffs, "I told you I was a BAD MAN!!"
After filming on Saturday, Justin Tweeted, "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. ;)"
But not everyone had a good time on-set. Justin Tweeted, "And this guy?? He did not have such a great day. Lol. Thanks to everyone at CSI for having me," along with this picture:
