The couple had formally separated two years ago. She's seeking legal and physical custody of their two daughters, ages five and eight, while allowing Russell visitation rights, although she asks he be, quote, "accompanied at all times by the childen's nanny and security personnel." Thirty-two-year-old Kimora and 50-year-old Russell tied the knot in December of 1998.

While Russell Simmons made his name as a pioneering rap and hip-hop producer, former owner of Def Jam Records and creator of Russell Simmons Def Comedy Jam, Kimora has had success as a model, judge on America's Next Top Model and star of her own reality series, Kimora: Life in the Fab Lane. She also has her own fashion line, called Baby Phat, and has created three perfumes, in addition to writing the book Fabulosity: What It Is and How to Get It.
