The wife of Grammy-winning singer Kenneth "Babyface" Edmonds has filed for divorce after 13 years of marriage, citing irreconcilable differences, court papers indicated.

Tracey Edmonds filed for divorce from her former husband Tuesday in Los Angeles County Superior Court. The couple had announced in October that they were ending their marriage with a "permanent separation" and said they had been separated for some time.

"We remain best friends," their statement then said.

Her attorney declined to discuss the matter Wednesday night. Kenneth Edmonds could not be reached for comment by The Associated Press.

The couple have produced movies and television shows together, including "Soul Food," and said in October they would continue to work together on business ventures.

Kenneth Edmonds, 47, and Tracey Edmonds, 37, married on Sept. 5, 1992. They have two sons: Brandon, 9, and Dylan, 4 1/2.

Tracey Edmonds, who as head of Edmonds Entertainment Group, Inc. is considered one of the most powerful women executives in Hollywood, is seeking physical custody of the boys, with visiting rights for her husband.

Besides his career as a best-selling crooner with hits including "Whip Appeal" and "Change the World," Edmonds has written hits for Whitney Houston, Mary J. Blige, Mariah Carey, Bobby Brown and others.
