I hate to post this in the Celebrity Section as I hate to pander to his ego and class him a celebrity but I couldn't think where else to put it! *Britney Spear's estranged husband Kevin Federline is reportedly refusing to sign their divorce papers. He is said to be concerned about Britney's relapse into her old lifestyle after her stint in rehab earlier this year and is worried about the well-being of their children. Although the divorce between the couple is yet to be finalised, they reached a "global divorce settlement on all issues of their marriage" in March in which the couple would share joint custody of their two young sons, Sean Preston, 21 months, and ten month old Jayden James. Said a source: "It's not about the money. It's her partying ways that is forcing Kevin to put his foot down." Yeah right - he's holding out for more money I think!!!
