Country Legend Glen Campbell Is Dead at 81

The singer died Tuesday in Nashville following a long battle with Alzheimer's Disease.

Country icon and original Rhinestone Cowboy Glen Campbell has died following a years-long battle with Alzheimer's, TMZ reports. The Arkansas native was 81.

The singer, whose career spanned 50 years, passed Tuesday morning at a Nashville facility for Alzheimer's patients, according to reports.

Campbell rose to fame in the 1960s and 70s with a string of hits that included "Galveston," "Wichita Lineman," and, of course, "Rhinestone Cowboy," picking up four Grammys in 1967 and marking a key crossover between the pop and country worlds. Amidst his hits and a 1968 Entertainer of the Year CMA, Campbell hosted his own CBS variety show, "The Glen Campbell Goodtime Hour," appeared alongside John Wayne in True Grit, and performed as a touring member of The Beach Boys.

In 2014, Campbell released the documentary I'll Be Me that documented the star's farewell tour and his struggle with his 2011 Alzheimer's diagnosis. He released his final album, Adiós, earlier this year. Campbell is survived by his wife Kim and eight children.
