Beloved jazz musician George Duke passed away on Monday at St. John's Hospital in Los Angeles. There is no word yet as to what caused Duke's unfortunate death at the age of 67. The Grammy Award-winning keyboardist is survived by his two sons Rasheed and John.

Fellow musician Scherrie Payne, co-lead singer of The Supremes, issued a note to the Motown Alumni Association that read:

I just received the devastating and sad news that the great musician, George Duke, passed away this evening at St. John's hospital in L.A. It was just one year earlier, July 18th, that his beloved wife and my friend, Corine, went to be with the Lord. Please keep his sons, Rasheed and John, in your prayers.

Funeral services will be private.

Blessings,
Scherrie

Although no official cause of death has been given, Duke's label Concord Music Group did say that he was battling chronic lymphocytic leukemia. In memory of his wife Corine, who passed away last year after a battle with cancer, Duke released his final album DreamWeaver on July 16.

"The outpouring of love and support that we have received from my father's friends, fans and the entire music community has been overwhelming," Duke's son Rasheed said in a statement.

"Thank you all for your concern, prayers and support."

Over the span of 40 years, Duke was known for his iconic funk and R&B fusion that led him to play alongside musical legends Michael Jackson, Miles Davis, and Frank Zappa. A number of Duke's songs have been sampled by today's musicians including Daft Punk, Kanye West, and Common.

Josh Groban, Questlove, and Justin Timberlake are just some of the celebrities who showed their support on Twitter:

I was fortunate enough to sing "They Won't Go When I Go" with George Duke. He was a master and a very kind guy. RIP
