Nelly will guest-star on two episodes of CBS's "CSI:NY," with the first appearance coming on Oct. 8.

While details of his role are being kept under wraps, the episode takes place when an air marshal is found dead shortly after takeoff on a New York to D.C. flight. Det. Mac Taylor, played by Gary Sinise, is onboard the plane and helps search for the killer and the murder weapon.

One hint: Nelly won't play the victim, he said during a Monday visit to Billboard's L.A. office. "You don't want to be the corpse, because you get the script and it's blank," he joked.

Nelly previously appeared in the 2005 film "The Longest Yard." His next album, "Brass Knuckles" drops on Tuesday.
