Britney Spears talking dirty to Kevin Federline

Star says Britney Spears has taken to having regular phone chats with ex-husband Kevin Federline. Phone sex chats, that is. Apparently she picked up the phone during one sleepless night to talk about Sean and Jayden when the talk took a turn. Now it’s a regular thing.

“They have phone sex often — at least once a week,” a source says. “The one thing those two have in common is their need for sex, and after they get going, there are no holds barred.” Time to block numbers!
