When you're a superstar like Justin Bieber, everything gets thrown your way -- including naked girls as well as a guest starring role on CSI!

When asked what the craziest thing a fan has done to get his attention, the Biebs said, "The girls show up wearing nothing. I can’t lie, I’m 16, I don’t hate it. I don’t have a girlfriend." But he did tell Vibe that "My mom has me on a tight leash and [she's] being real protective." So we're sure a quick peek was all he got!

But we'll get more than a quick peek at Bieber when he has a guest-starring role on the premiere of CSI!

Bieber will play "Jason McCann" reports ET "a troubled teen faced with a terrible decision regarding his only brother -- a decision that leads him into an explosive confrontation with the CSIs."

And apparently the producers are so jazzed about tapping into Bieber Fever that they already have more episodes planned!

"We're looking forward to Justin's dramatic star turn, not only in the premiere, but in a continuing seasonal arc," the exec producers said.

But is the world ready for a serious Justin?
