Britney Spears’ visitation schedule was expanded last week after she made a court appearance and was able to show the judge that she was ready to spend more time with her boys. Kevin Federline’s attorney, Mark Vincent Kaplan, recently said that the relationship between his client and Britney is improved and that they’re getting along better. He was optimistic but guarded in the way he described Britney and Kevin’s relationship, and People quotes him as saying “there will be some contact … there’d be some ability to exchange a camaraderie that is necessary and a function of co-parenting together.”

Was Kaplan just giving a general non-committal answer to a question or was he saying in lawyer-speak that Britney and K-Fed are knocking boots again?

Star Magazine claims that the exes are having phone sex late at night, which would be a follow up to their earlier probably-fake story that K-Fed and Britney shared a kiss during a meeting about their boys.

“[Britney and Kevin] have phone sex often – at least once a week,” says an insider. And while [it] often begins with innocent conversations about matters like their sons… or plans for the future, “The one thing these two have in common is their need for sex, and after they get going, there are no holds barred.”

Typically, Britney makes the first move by calling Kevin. Bit he initiates the titillating chatter, playing on the pop star’s soft spot for sex. “She often contacts Kevin on Monday nights, usually because she’s recovering from a lonely weekend and feeling insecure,” adds the insider.

“He’s used to getting the calls and knows just how to get the sultry talk started.”

Star claims that Kevin wants to have sex with Britney but that she’s holding back and sticking to phone sex because she’s afraid of what might happen if she falls for K-Fed again.

Federline has probably moved on in his life and isn’t likely to be interested in Britney anymore, but he’s also the type of guy who would easily go back to an ex. It seems like he’s more than just friends with his ex, Shar Jackson, and you can see him being unable to pass up a free refill. If Britney and Kevin do get back together you can bet that a lot more tabloids than Star will be talking about it.
