Singer Linda Ronstadt has canceled tour dates for the rest of the year to recover from surgery she had this week, her agent said Thursday.

Ronstadt's agent, Shelly Schultz, would not provide details on the surgery the longtime performer underwent Tuesday in Tucson, Ariz., but said it wasn't cancer.

"It wasn't an emergency, but it came about rather quickly, so she decided to do it sooner rather than later," Schultz said. "It's surgery, it's completed, and she's fine."

Ronstadt, 60, was scheduled for various performances from September through October, Schultz said.

Ronstadt will recuperate at her home in Tucson for an "undetermined" amount of time, Schultz said. Then she'll travel back to her other home in San Francisco to spend time with her adopted children Carlos, 9, and Mary, 13, said Schultz.

A native of Tucson, Ronstadt is known for hit albums such as "Heart Like a Wheel" and "What's New."
