Nancy Wilson divorcing Cameron Crowe

Couple has been married for more than 20 years

A longtime Hollywood couple has called it quits.

Heart singer-guitarist Nancy Wilson filed for divorce from writer-director Cameron Crowe, according to court records cited by the Associated Press.

The documents, filed Sept. 16, cite irreconcilable differences as the reason for the split, adding that the couple separated in 2008.

Wilson and Crowe were married in 1986. Wilson is seeking joint custody of their twin 10-year-old sons.

Crowe's credits include "Jerry Maguire" and "Say Anything." He won an Oscar for writing "Almost Famous."

Heart, known for such hits as "Magic Man" and "Alone," also includes Wilson's sister, Ann.
