Mashonda is not letting Swizz Beatz walk away lightly. The R&B star is battling her estranged husband in court, demanding increased child support payments to care for their two year old son. Mashonda split from the hit producer in April 2008 after four years of marriage and she filed for divorce in February (09). Mashonda claims the support is insufficient to care for their two kids after the Swizz allegedly slashed his monthly payments from $5,000 a week to $3,500 a month. “An application is pending before the court, where the facts will be developed,” says Mashonda’s attorney, Bernard Clair The split couple has also been disputing about bills for Mashonda’s mansion in Westchester, New York, after Swizz allegedly refused to pay to repair the heating during the winter. A pal of Swizz Beatz tells the New York Daily News, “The house is 30,000 square feet. The heat didn’t work in one wing, not where Mashonda and Dean slept. Swizz had been paying all of their bills. On top of that, he was giving her $5,000 a week. His advisers felt that was too much, so now he pays her $3,500 a month, on top of the bills. “Swizz has put settlement offers on the table, but Mashonda won’t say what she needs. She just came back from Paris and London. She drives a Bentley Flying Spur and a Cadillac Escalade. I don’t think life’s too bad for her.” Beatz’s lawyer, Dan Rottenstreich, adds: “He’s taken care of her and his son above and beyond what’s required.” Swizz Beatz is reportedly dating Alicia Keys
