Say it ain’t so for humanity: Kevin Federline’s girlfriend, Victoria Prince, is pregnant, according to reports. If true, it would be K-Fed’s fifth freaking child. Federline already has four children - daughter Kori, 7, and son Kaleb, 5, with former flame Shar Jackson, who he infamously dumped for Britney Spears. The pop star soon bore him troubled sons Sean, 4, and Jayden, 3. Victoria Prince, a former pro volleyball player, has been living with Kevin Federline since this spring for some reason, and just learned she is knocked up. She began to suspect she was pregnant after the two spent a weekend in Las Vegas in mid-October. Her fat slob BF urged her to take a pregnancy test. It was positive. As if there were any doubt. Guy’s boys can swim! K-Fed is totally pregnant. Er, we mean Victoria Prince is. Yeah … “The test was positive. She told Kevin that she was pregnant, but he didn’t seem happy to hear the news,” a source quoted by the National Enquirer says. “Kevin wasn’t planning to have children with Victoria, and he’s upset with her. Kevin loves her, but he told her that he didn’t want to get married again.” What’s more, another source says the baby news could send the emotionally fragile Britney Spears, who long hoped for a reconciliation, back off the rails: “Britney never wanted Kevin to have another child unless it was with her. She desperately wants a baby girl, and she had hoped Kevin would be the dad.” We’re not sure if we believe that part. She and Jason Trawick seem very happy together, and come on, it’s Kevin Federline. Who would want that back? Seriously, Victoria Prince. What is the appeal? OMG check out that random, overweight, chain-smoking deadbeat slob with no job and four kids! HOT!
