Federline to return to 'One Tree Hill'

Kevin Federline has been asked to become a regular character on teen US TV show One Tree Hill after he impressed producers with a one-off cameo performance.

Britney Spears' ex-husband played a frontman for a rock band in the show and was first seen acting in a small part for CSI: Crime Scene Investigation last year.

Federline said: "I've had a great time doing it. I didn't really know I'd have as much fun as I did.

"I've shot two (episodes) already and I've got to go out and shoot one more. We'll see where it takes me."

Federline, who is currently battling it out for the custody of his two sons with Spears in court, has also tried to launch a rapping career, but admitted that he has been concentrating on acting for now.

He said: "I like doing it all. Music is a passion to me but I'm finding my passion in acting right now."
