The dysfunctional relationship that is Britney Spears and Kevin Federline has just gotten stranger. That is, if you want to know about their sex life.

Even though the two are in the middle of a custody battle, they have remained close and call each other often. But Star Magazine reports that these frequent calls aren’t always to talk about the kids.

Let me just preface this by saying READ AT YOUR OWN RISK!

The magazine reports:

“Recently, when Britney was having a sleepless night, she decided to call Kevin at nearly 2 a.m. While they initially chatted about their boys – Preston, 2, and Jayden, 20 months – the conversation shifted. And as Britney hoped, Kevin knew exactly how to tire her out – with hours of erotic talk! “They have phone sex often – at least once a week,” an insider tells Star. “The one thing those two have in common is their need for sex, and after they get going, there are no holds barred.”

So I bet that’s some information you might not have wanted to know about these two. But really the question I want to ask is, how does Star Magazine know all these intimate details? I really doubt Britney called them up herself and told them this story. I guess I wouldn’t put it past her, but I think she needs all the good publicity she can get.

Honestly, though, this is really too much information. Why would anyone but Britney and Kevin need to know this? Or would want to? Some things are better left unsaid.
