"Many hearts are broken today, including my own, with the death of one of my dearest friends, Mac Davis," she wrote alongside a photo of the two together. "We lost one of the world’s greatest writers, singers, and entertainers."
She adds, "My love and sympathy goes out to Lisë, his precious wife, his children, and his grandchildren. Rest in peace, my friend. I will always love you, Dolly."
"It's with a heavy heart that I announce the passing of Mac Davis," the statement says. "He was surrounded by the love of his life and wife of 38 years, Lise, and his sons Scott, Noah and Cody."
The musician rose to prominence as a country singer-songwriter in the '60s and '70s. He's best known for writing hits like "In the Ghetto" and "A Little Less Conversation" for Elvis Presley, "Everything A Man Could Ever Need" for Glen Campbell and "Something's Burning" for Kenny Rogers and The First Edition. Davis collaborated with Parton on "White Limozeen," the title track from her 1989 album. The two also co-wrote another song on the same project called "Wait 'Til I Get You Home."
In 1998 Davis' extensive contributions earned him a star on the Hollywood Walk of Fame and in 2000 he was inducted into the Nashville Songwriter's Hall of Fame.
