Rocker Nancy Wilson Divorcing Cameron Crowe

Director Cameron Crowe and his musician wife, Nancy Wilson, are pulling the plug on their 22-year marriage.

Wilson, a singer and songwriter from the rock band Heart, filed divorce papers Thursday in L.A. County Superior Court, citing irreconcilable differences. She lists June 15, 2008, as the date of their separation.

Crowe, who directed Jerry Maguire and Almost Famous, married Wilson July 23, 1986. The couple have 10-year-old twin boys, William and Curtis.
