Britney Spears' estranged husband Kevin Federline has turned down a $25 million (GBP12.8 million) divorce settlement offered by the pop star, according to media reports in the US. The former back-up dancer was reportedly looking for a $50 million (GBP26 million) settlement from the TOXIC singer and the mother of his two children, Sean Preston and JAYDEN JAMES. A source tells American publication Star, "Kevin says that Britney offered him $10 million (GBP5 million) to walk away from their marriage and to relinquish custody of their kids, but he just laughed. "Then she came back with $20 million ($10.3 million), which he turned down, too. Now he says she's offering a whopping $25 million (GBP12.8 million) and that's her final offer. He told her to take a hike!" Part of the settlement offered by Spears reportedly includes a condition that would have Federline severing his ties with his young sons. The sources adds, "He loves his two little boys, and there's no way he's going to disappear from their lives."
