First dancing, then rapping. What will Kevin Federline do next?

Looks like the 28-year-old husband of singer Britney Spears will be shuffling over to the small screen where he will appear in an episode of "CSI: Crime Scene Investigation" this fall, People magazine reported.

Although he and Spears ventured into TV with their reality show "Chaotic," which aired on UPN last year, Federline said this will be his first venture into acting.

"It's the first time I've actually had a speaking role," he told the magazine.

Federline started filming this week in Los Angeles. He will play a menacing, arrogant teen who harasses investigators Nick Stokes (George Eads) and Warrick Brown (Gary Dourdan) on a job.

The episode is tentatively scheduled to air in October.

Federline recently performed at the Teen Choice Awards where he rapped one of the songs on his upcoming album "Playing with Fire."
