Tracey Edmonds, the wife of Grammy-winning R&B singer Kenneth "Babyface" Edmonds, has filed for divorce after 13 years of marriage.
The papers, filed in Los Angeles County Superior Court on Tuesday, cite irreconcilable differences as the reason for the split, the Associated Press reports. The couple announced in October that they were ending their marriage, and that they had been separated for some time.
"It is with deep regret that we announce our permanent separation. We remain best friends," they said in a statement at the time.
The Edmonds have produced movies and television shows together, including Soul Food. They plan to continue working together on business ventures.
Kenneth Edmonds, 47, and Tracey Edmonds, 38, married on Sept. 5, 1992. They have two sons: Brandon, 9, and Dylan, 4. Tracey is seeking custody of the boys, with visiting rights for her husband.
Babyface's hits include "Whip Appeal" and "Change the World."
