Britney Spears and Kevin Federline Have Phone Sex!

Britney Spears only has partial custody of her kids right now, and she is only sort of talking with K-Fed now. This however doesn't stop the two from having casual phone sex...Yummy?

"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."

What is more erotic then a trailer park couple grunting over the phone? A midget masturbating in a corner, a fat guy lubing himself in oil, Star Jones naked...ok maybe that's a stretch.
