He’s one of the busiest entertainers in show business, but Justin Bieber made sure to make time to guest star on the upcoming season premiere of “CSI.”

And according to executive producer Carol Mendelsohn, it was a treat to have the “Baby” singer join their team, though it was only for a short time.

She told press, "I got a call that Justin really was a fan of 'CSI' [and] that's all I have to hear, and so it just was perfect timing. Justin was looking to make his dramatic acting debut. We had an incredible role for a young actor in [our season premiere], so it just seemed like the perfect marriage."

"There was one day that Justin had available and that was the day he came to 'CSI' and filmed his four scenes for the premiere. We will introduce his character in the premiere in September and then it will be a character arc and we will see him again playing Jason McCann again in February."
