Linda Rondstadt has Parkinson's disease, can't sing

Singer Linda Rondstadt told AARP in a report published Friday that she can no longer sing because she has Parkinson's disease.

Rondstadt, 67, said she was diagnosed eight months ago but has had symptoms as long as eight years. She said she was losing her voice but thought it had to do with a tick disease she suffered from for years. She thought her trembling hands had to do with a shoulder operation.

She said she was "completely shocked" when she finally saw a neurologist and was diagnosed with Parkinson's disease.

Rondstadt has a memoir coming out in September 2013. The book, Simple Dreams, doesn't talk about Parkinson's or her voice issues, she told the AARP.

The singer has had a successful music career since the 1960s and also grabbed headlines in her youth for her dating life. She went out with Calif. Gov. Jerry Brown when he ran for president in 1980 and later was engaged for awhile to Star Wars creator George Lucas.

Ronstadt sold tens of millions of records starting in the 1970s with pop hits like "You're No Good" and "When Will I Be Loved."
