The passing of Andrew, the son of composer Steve Dorff and the brother of the actor Stephen Dorff was announced in a post on the Facebook page of the Nashville Songwriters Association International (NSAI) on Tuesday (20Dec16).

"It is with immeasurable grief that we learn of the passing of our friend Andrew Dorff," NSAI President Lee Thomas Miller wrote in the message.

Steve, 67, later confirmed the death of his son in an emotional post on his own Facebook page.

"Thank you all for the outpouring of love and prayer," he wrote. "There simply are no words for the unbearable heartbreaking loss my family and I are feeling today. May God bless my Son Andrew, the best friend any Father could have. Your light will forever shine in my heart, and in all those who were lucky enough to know you."

Andrew penned tracks for a number of country stars including Blake Shelton, Justin Moore, Kenny Chesney and Tim Mcgraw.

Upon hearing of the tunesmith's death, stars of the country music world were quick to pay tribute to him on Twitter.

"The Nashville songwriting community lost one of its finest talents + kindest souls today," vocal duo Dan + Shay wrote on the social media site, while singer Chase Rice added, "No words. Andrew Dorff I don't even know what to say man. Heart broken (sic). You'll be missed. A great songwriter taken way too young."

Martina MCBride, whose 2009 country hit Ride was co-written by Andrew, remembered, "So very sad to hear about @endorffin (Andrew's Twitter handle) Thanks for caring enough to write with me and for "Ride" #shinewhileyouhavethechancetoshine #sweetsoul (sic)."

Among the hits Andrew worked on include Blake’s 2014 track Neon Light, which topped Billboard's U.S. Country Airplay chart.

No cause of death has been reported.
