Trace Adkins' father has passed away, just days after the singer departed rehab to be with him during his illness.

Aaron Adkins died over the weekend, according to comments on Trace Adkins' Facebook page. The singer's wife, Rhonda, took to Twitter Monday morning (Feb. 3) to thanks fans and well-wishers for their support.

The elder Adkins was a longtime mill worker. His famous son has often credited him with not only his work ethic, but also his love of country music.

“Growing up, I listened to everything that my daddy owned in his collection of country music,” Adkins recalled to GAC. “Waylon Jennings, Merle Haggard, George Jones, Johnny Cash, Jerry Reed, Buck Owens -- those legendary guys that were hot back then. He had all that stuff, and that’s most of what I listened to.”

Adkins' cause of death has not been revealed. No funeral plans have been announced publicly.
