Andrew Dorff, the in-demand Nashville songwriter who penned hits for Blake Shelton and Kenny Chesney has died.

The Los Angeles-born Dorff, who was the brother of actor Stephen Dorff was 40.

The cause of death has not been disclosed, but on a recent interview with Larry King, Stephen Dorff had this to say about his brother’s death:

“We don’t know officially, but there was some drinking involved, there was a Jacuzzi involved, and there was water involved,” Dorff said. “Andrew was splashing around … and somebody spotted him laying on his back, not moving. They brought him onto the beach, some stuff happened, and I don’t really — can’t really — get into the particulars, but all I know is, my brother should be here, and he should be enjoying his success.”

The Dorff brothers recently collaborated for a song called “Pour Me Out Of This Town” which is featured in the film “Wheeler” wherein Stephen Dorff plays a country singer alongside Kris Kristofferson.

“What a beautiful community,” Dorff told King about his brother’s life in Nashville. “I didn’t really understand what my brother knew as a community of songwriting.”

The Nashville Songwriters Association International president, Lee Thomas Miller paid tribute to the songwriter on Facebook, penning these words: “Andrew was a good man and a good friend. He was an elite songwriter at the peak of his life and career. Our sincerest prayers go out to his family. May we all hug each other a little tighter this week and remember that life is fragile.”

Dorff’s father Steve Dorff is a Grammy and Emmy Award nominated songwriter.
