UPDATE: The duo's divorce was finalized Dec. 8 after they reached an out-of-court settlement with a mediator.
Nancy Wilson apparently just wants to get herself alone.
The Heart singer has filed for divorce from director hubby Cameron Crowe after nearly 24 years of marriage and a fruitful creative partnership, citing irreconcilable differences.
One of those differences being their respective addresses for the past two years, so it turns out.
In her petition, filed Sept. 16 in L.A. Superior Court, Wilson cites their date of separation as June 15, 2008.
Perhaps the singer-songwriter, who produced and composed music for a number of her husband's films, finally wanted a clean break before their silver anniversary rolled around.
She and Crowe are parents to 10-year-old twin sons, William and Curtis. Wilson is asking the court for joint custody and the restoration of her legal name to Nancy Lamoureaux Wilson.
Nancy and her sister Ann Wilson have been rocking out as Heart since the early 1970s.
