Kenny G and his wife of two decades are officially done making beautiful music together.

TMZ reports that the jazz musician (real name: Kenneth Gorelick), 56, filed for divorce from his wife, Lyndie Benson-Gorelick, August 9, citing irreconcilable differences.

The pair -- who have been married for more than twenty years and have two children together -- first separated in January, after Lyndie filed for separation.

In the documents, Kenny requests joint legal and physical custody of the couple's minor son; TMZ says the papers filed by the saxophonist (who is worth an estimated $50 million) also indicate he and his wife had a prenuptial agreement.
