Hip-hop star Sean “P. Diddy” Combs has been ordered to pay more than $21,000 a month in child support to an ex-girlfriend with whom he has an 11-year-old son.

The order, issued Thursday by the New York Supreme Court’s Appellate Division, came after Combs appealed a Westchester Family Court ruling last year that he should pay $35,000 a month. He currently pays about $5,000.

The ex-girlfriend, Misa Hylton-Brim, had sued for higher monthly payments and about $398,000 in back support for their son, Justin.

The appellate court judge awarded a lower but undisclosed amount in back support and ordered Combs to pay Hylton-Brim’s legal fees. The judge set monthly support payments at $21,782.

Rob Shuter, a spokesman for Combs, said Combs would appeal the decision to the state Court of Appeals.

While separated from girlfriend Kim Porter, Combs, 35, was also sued for child support for their son, Christian. He pays Porter, a model, about $30,000 a month.
