Britney Spears' ex-husband Kevin Federline is to become a father again, according to reports.

The former dancer's girlfriend, Victoria Prince, who he has been dating since last year, is reportedly several weeks pregnant with the pair's first child.

But Federline, who has two sons with Spears, as well as two children with ex-girlfriend Shar Jackson, is reportedly unhappy at the baby news.

A source tells the National Enquirer, "The test was positive. She told Kevin that she was pregnant, but he didn't seem happy to hear the news."

While another source tells Star magazine, "Victoria's been ill off and on, so everyone suspects that she's expecting. Under no circumstances does he want another kid now. He's not even acknowledging the possibility. He's awful when it comes to birth control. Kevin thinks it's the woman's responsibility."
