Kevin Federline is to be a father for the fifth time, it has been claimed.

Britney Spears’ ex-husband is said to be having a baby with his girlfriend Victoria Prince.

Former backing dancer Federline, 31, already has two sons with Spears - Sean Preston, four, and Jayden James, three.

He also has a daughter, seven-year-old Kori, and a son, Kaleb, five, with his former partner, Shar Jackson.

A source said Prince broke the news to Federline after getting a pregnancy test.

The insider told a US magazine: “The test was positive. She told Kevin that she was pregnant, but he didn’t seem happy to hear the news.”

Federline, who has been dating volleyball player Prince since last December, is set to appear on American television’s Celebrity Fit Club.

His representative was unavailable for comment.
