Wild woman Britney Spears' grungy ex-hubby, Kevin Federline, is starting a three-episode role Tuesday on “One Tree Hill."
On the teen-scream series, K-Fed plays Jason, the “cocky, enigmatic" frontman for an up-and-coming rock band — called No Means Yes — from the show's fictional town of Tree Hill, NC.
He certainly looks the part. K-Fed even shaved his head in a mohawk-style cut for that tough-guy look, offset by tattoos and heavy jewelry.
Federline shot his scenes on location last October in Wilmington, Del., before the worst of the pop tart's public meltdowns — the latest ending up in the psychiatric wing of an LA hospital.
Fellow cast members say Federline was all business when he showed up on the set.
“He brought his mom to the set," said “Hill" star Hilarie Burton. “He worked really, really hard and was totally there to act," she told a reporter. “He wasn't there to make a spectacle of himself or to party or anything."
