Although Justin Bieber is currently prepping for his number at Sunday night’s VMAs, we can see him perform now in an entirely different arena.

Later this month, the singer will guest star on one of his favorite shows. “Watching CSI growing up was really fun for me and my mom just sitting in our apartment,” the 16-year-old said about the hit CBS series. “I liked it because you never knew what was going to happen. Now that I’m on it, it’s pretty cool.”

Get a sneak preview of Bieber playing “bad kid” Jason McCann in the behind-the-scenes video above.
