LOS ANGELES (AP) — Kimora Lee Simmons has by now moved on, but she took steps to make it legal by filing for divorce from her husband of seven years, entertainment mogul Russell Simmons.

Although the pair 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 enquiring into legal and physical custody of the kids. She asked that Russell Simmons be given “acceptable child visitation … accompanied at all times by the children’s nanny and security personnel.”

Russell Simmons co-founded Def Jam records and creator of Phat Farm clothing and HBO’s “Def Comedy Jam.”

Kimora Lee Simmons has been seeing actor Djimon Honsou.
