Singer Linda Ronstadt has cancelled the remaining dates on her current tour after undergoing surgery in the US.
Ronstadt began her recording career in the 1960s
The 60-year-old star was treated in hospital in Arizona on Tuesday, her agent, Shelly Schultz, told the Associated Press news agency.
Ms Schultz refused to disclose details about the surgery, but said that it was not for cancer.
Ronstadt - best known for albums such as What's New - was due to perform gigs in September and October.
They included dates in Mexico and Texas.
Speaking about the surgery, Ms Schultz said: "It wasn't an emergency, but it came about rather quickly, so she decided to do it sooner rather than later.
"It's surgery, it's completed, and she's fine."
Ronstadt will recuperate at her home in Tucson, Arizona, for an "undetermined" amount of time, and then travel back to her other home in San Francisco to spend time with her adopted children, Ms Schultz added.
