Another baby for KFed?

Kevin Federline is going to be a father for the fifth time.

The aspiring rapper - who has sons Sean Preston, four, and Jayden James, three, with ex-wife Britney Spears and Kori, seven, and five-year-old Kaleb with former girlfriend Shar Jackson - was reportedly unhappy when current partner Victoria Prince broke the news she is pregnant.

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

Kevin - who has been dating the volleyball star for just under a year - is said to be desperately unhappy about welcoming a child into the world.

Another insider said:  "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."

Kevin and Victoria have not confirmed the pregnancy, however pals admit they have had their suspicions about the sportswoman's condition for several weeks.

One pal explained: "Victoria thought she was pregnant after she felt sick after lunch one day. Victoria's been ill off and on, so everyone suspects that she's expecting."
