Kevin Federline in talks to star in Broadway version of Legally Blonde

Britney Spears' ex-husband Kevin Federline is reportedly in talks to star in the Broadway version of Legally Blonde.

Sources close to Federline say the 30-year-old may be heading to New York in September to make his Broadway debut in the the Tony-nominated musical adaptation of the hit film.

"He’s so excited!" a Federline source tells Us Weekly magazine in its latest issue.

Federline — a former backup dancer — has recently been hitting the gym to shed some "daddy weight," his former fiancee & mother of his two children, Shar Jackson says — and he will test his song-and-dance chops in a trio of roles — including the UPS guy who inspires the "bend and snap."

"This is his chance to show the world what he can do," adds the pal.

And in a move that is likely to shock Britney, K-Fed and the troubled singer's sons, Sean, 2, and Jayden, 18 months, might join him in the Big Apple.

Adds the source: "This is his dream and he wants to bring the kids,” says the insider. "Jamie and Lynne [Spears] promised to help him make it work."

A rep for the show says he is not scheduled “as of this time.”
