Singer Linda Ronstadt has revealed she is battling Parkinson’s Disease and says the effects have left her unable to sing.

The 67-year-old singer, best known for her songs “You’re No Good” and “When Will I Be Loved,” revealed her diagnosis to AARP, saying she sought medical advice after experiencing problems with her voice. “Parkinson’s is very hard to diagnose, so when I finally went to a neurologist and he said, ‘Oh, you have Parkinson’s disease,’ I was completely shocked. I wouldn’t have suspected that in a million, billion years,” she said.

Ronstadt, who was diagnosed eight months ago, now sometimes requires walking assistance and “can’t sing a note,” she said. “No one can sing with Parkinson’s disease,” Ronstadt said. “No matter how hard you try.”

A full interview with Ronstadt will appear on the organization’s site next week, and her memoir, Simple Dreams, will be out in in September (though, the AARP story notes, the book does not address her diagnosis).
