Britney Using Isaac Cohen to Make FedEx Jealous?

Are the parents of Jayden James Federline officially over?

Maybe not. Britney Spears has been making late-night phone calls to K-Fed in hope of a reconciliation, according to several of Kevin's close peeps.

The friends of Kevin, who understandably requested anonymity, told TMZ that Britney's relationship with Isaac Cohen is a ruse to make Kevin jealous.

But other sources - and surely ones with more brain cells - say Britney is so over Kevin Federline. They say that Britney and Fedex have very little contact, and when they do communicate, it's about their two kids.

The two will continue to share custody of their two young sons this month, following the terms of a January custody agreement, Federline's attorney confirmed Thursday.

The temporary agreement has been extended through February, according to publicist Michael Sands, speaking on behalf of K-Fed's attorney, Mark Vincent Kaplan.

Per the terms of that agreement, good ol' Kev will continue to be allowed to visit Sean Preston and Jayden James Federline at Spears' home from noon to 4 p.m. on Mondays, Wednesdays and Fridays.

By the way, according to the same sources, recent reports that Britney will ante up a $25 million settlement to K-Fed to end their marriage are ridiculous.

One connected source says the $25 million figure is grossly inflated. About 25 times inflated.

In other words, the bad news is that FedEx will probably become a millionaire.

But the good news is that he won't be a multi-millionaire... at least not from Britney. He's doing well for himself with these fast food gigs though.
