Britney Spears' ex-husband Kevin Federline is set to become a regular fixture on TV drama series One Tree Hill after impressing cast and crew with his acting skills. The rapper/dancer has already filmed a guest role on the show and thoroughly enjoyed himself. And now Federline, who made his acting debut on CSI: Crime Scene Investigation last year (06), is set for more appearances on the hit teen soap. He says, "I've had a great time doing it I didn't really know I'd have as much fun as I did doing it. "I've shot two already and I've got to go out and shoot one more... We'll see where it takes me." Federline reveals he has put his pop career on hold to concentrate on his love for acting. He adds, "I like doing it all. Music is a passion to me but I'm finding my passion in acting right now."
