Country music legend and Hall of Famer, Glen Travis Campbell, has died at the age of 81 following a fight with Alzheimer's disease.

His official website shared the news of the "Rhinestone Cowboy" singer's death at the age of 81.

"It is with the heaviest of hearts that we announce the passing of our beloved husband, father, grandfather, and legendary singer and guitarist, Glen Travis Campbell, at the age of 81, following his long and courageous battle with Alzheimer's disease," the statement read.

The legendary singer and guitarist is survived by his wife, Kim Campbell of Nashville, their 3 children, Cal, Shannon and Ashley.

He's also survived by his children from previous marriages, Debby, Kelli, Travis, Kane, and Dillon; ten grandchildren, great-and great-great-grandchildren; sisters Barbara, Sandra, and Jane; and brothers John Wallace 'Shorty' and Gerald.

Campbell's career spanned six decades and, according to Rolling Stone, in 1968 he sold more records than the Beatles did that year.

In 2011, Campbell revealed that he was diagnosed with Alzheimer's disease.
