Kenny G has filed for divorce, TMZ reports.

The musician's estranged wife, Lyndie Benson-Gorelick, originally filed for legal separation in January after 20 years of marriage.

Kenny G cited "irreconcilable differences" with his soon-to-be ex-wife, with whom he shares two sons -- the 56-year-old saxophonist is asking for joint custody of their minor child.

According to divorce documents, Kenny G, who is worth an estimated $50 million, did have a prenup agreement with Benson-Gorelick.

Celebrity divorce lawyer Lauren Wasser (who has represented the likes of Britney Spears, Christina Aguilera and Angelina Jolie) filed the documents.
