Kimora Lee Simmons and Djimon Hounson break up?

Kimora Lee Simmons and Djimon Hounsou aren’t as committed to each other as they used to be. A source close to the couple tells us the glamazon and her “Gladiator” beau have split after a “big fight over money.” “Djimon walked out on Kimora,” says the source, who adds that the split may have been prompted by Simmons’ ex-husband, hip-hop mogul Russell Simmons ’ decision to stop funding the pair’s lifestyle. St. Louis-born “Kimora lives as if she’s the Queen of England.” Over the Christmas and New Year holidays, another source who saw Hounsou and Simmons in St. Barth noticed tension between them. At a party that Kimora’s ex threw at the Eden Roc hotel there, “Kimora stuck Djimon with keeping track of the three kids while she socialized with her ex,” the source says, adding that “Kimora and Djimon were fighting on New Year’s Eve.” “He is a calm, super-nice person and she’s such a diva,” says the source. “I couldn’t believe they got together in the first place.”
