LOS ANGELES – Court records show rocker Nancy Wilson has filed for divorce from writer-director Cameron Crowe after more than 20 years of marriage.

The Heart singer-guitarist cited irreconcilable differences for the divorce, which was filed Sept. 16.

The court filings say Wilson and Crowe separated in 2008.

They were married in 1986 and have twin 10-year-old sons. Wilson is seeking joint custody.

Crowe is known for directing films such as 'Jerry Maguire' and 'Say Anything.' He won an Oscar for writing the screenplay for the film 'Almost Famous.'
