LOS ANGELES - Kimora Lee Simmons has already moved on, but she took steps to make it official by filing for divorce from her husband of seven years, entertainment mogul Russell Simmons.

Although the couple separated in March 2006, Kimora Lee Simmons just filed divorce papers Tuesday in Los Angeles Superior Court. The 32-year-old Baby Phat fashion designer and reality TV star cited irreconcilable differences.

She and Russell Simmons, 50, have two daughters: 8-year-old Ming Lee and 5-year-old Aoki Lee. Kimora Lee Simmons is seeking legal and physical custody of the children. She requested that Russell Simmons be granted "reasonable child visitation ... accompanied at all times by the children's nanny and security personnel."

Russell Simmons co-founded Def Jam records and created Phat Farm clothing and HBO's "Def Comedy Jam."

Kimora Lee Simmons has been dating actor Djimon Honsou.
