(hollywood.com) - Sean 'Diddy Combs' ex-girlfriend Kim Porter is seeking $1 million a year in childcare for their three children, according to reports. Model Porter ended her 10-year romance with the hip-hop star last week and is now hoping to claim maintenance for their children--Christian, 9, and seven-month-old twin daughters D'Lila Star and Jessie James. A source tells Britain's Daily Mirror, "(His children) mean everything to him and any decisions taken here will have their best interests at heart." A spokesman for Combs says, "Anything like this (settlement) is pure speculation." Combs already pays $30,000 a month to Misa Hylton Brimm, the mother of his other son, Justin.
