EXCLUSIVE: Dolly Parton's Shocking Setback — 80-Year-Old Country Star's Comeback Derailed by Devastating Health Issues

Ailing Dolly Parton was forced to cancel her rescheduled Las Vegas residency due to yet another devastating health setback as fears grow that the 80-year-old country legend may never perform onstage again, RadarOnline.com can reveal.

The hard-working 9 to 5 songbird broke the bad news to fans on social media. She confessed medical treatments were leaving her too "swimmy-headed" to go on with the shows slated for September at the Colosseum at Caesars Palace, adding: "Of course, I can't be dizzy carrying around banjos, guitars and such on five-inch heels."

While Parton insisted she's "responding really well to meds and treatments" and "improving every day," she also admitted: "It's gonna take me a little while before I'm up to stage-performance level."

Doctors warned Parton is pushing herself too hard.

"It's good to keep moving, but she has to cut back on the time and pressures of her work if she wants to extend her life," said longevity expert Dr. Gabe Mirkin, while New York internist Dr. Stuart Fischer warned: "She has to choose between health and career if she wants to survive."

Neither doc has treated her.

Even Parton admitted her digestive and immune systems got "all out of whack" over the last three years.

Shortly after the March 2025 death of Carl Dean, 82 – Parton's beloved husband of 58 years – the Nashville icon was diagnosed with kidney stones and an associated infection and canceled multiple engagements, including an in-person appearance at the Governors Awards in November to accept the Jean Hersholt Humanitarian Award.

Now, insiders said the normally bubbly singer has been a shadow of her formerly vibrant self.

"Dolly is devastated that she's letting her fans down. It was the last thing she wanted to do, but the doctors told her flat-out that she's in no condition to be tearing around on stage right now," an insider confided.
