So Britney wasn’t just sick of bearing Kevin’s babies constantly, she also couldn’t bear that he was having sex with a porn star. That’s what Star mag has uncovered from a “source,” who says that K-Fed and “porn-star-turned-exotic dancer” Kendra Jade were having “a sex-fueled affair!” Mm, that “sex-fueled” part sounds hot; we’d like to fuel up on some of that ourselves if we knew where it was being pumped. Anyone? Anyway, report says the couple, Brit and K-Fed, were living apart by October, and K moved into a friend’s apartment in Studio City and began giving it to Kendra, whom he had met last December in Las Vegas. And then…er, oh dear, we’ve actually lost interest right in the middle of writing this. If you want more, it’s here. But one last thing: Isn’t the usual route exotic dancer to porn star? Is Kendra devolving into a schoolmarm?
