Rumer Willis, Chris Daughtry and Scott Wolf are lined up to appear on CSI: NY’s 100th episode.

Rumer will be playing the victim of a stalker, while Chris surprisingly enough plays a musician.

“Rumer was a delight,” the show’s executive producer Pam Veasey told TV Guide. “She was excited to be part of our episode and was quite the professional.”

Chris loved every minute of his first acting role.

“I loved every minute of playing a rock dude. I would love to act again, and hopefully after people see this, they’ll actually wanna see me act again,” he said.

Gary Sinise, who plays lead character Detective Mac Taylor, loved that American idol star agreed to come on the show.

“This is Chris’ first role. He was very natural and fit right in,” he said. “This is an episode my kids, who are all big American Idol fans, are actually going to watch.”
