It's official -- after 24 years of marriage, writer-director Cameron Crowe and singer Nancy Wilson are over.

Separated since June 2008, Wilson, 56, cited "irreconcilable differences" when she filed for divorce in September. The former couple's divorce was finalized amicably by a retired judge in L.A. Wednesday.

Known for films such as Jerry Maguire, Say Anything and Almost Famous, Crowe, 53, shares 10-year-old twin sons, William and Curtis, with the Heart rocker.
