Dolly Parton announced Sunday that she would be delaying six concerts at Caesars Palace in Las Vegas that were slated for December due to “health challenges.”

In a message posted on social media, the country superstar shared that she’s been dealing with some health issues and her doctors have advised her to undergo some procedures to manage it, though she did not provide specifics. The concerts were set for Dec. 4 through 13.

“I want the fans and the public to hear directly from me that, unfortunately, I will need to postpone my upcoming Las Vegas concerts,” the 79-year-old singer and songwriter wrote in a cheeky statement posted to her Instagram and X accounts. “As many of you know, I have been dealing with some health challenges, and my doctors tell me that I must have a few procedures. “As I joked with them, it must be for my 100,000-mile check-up, although it’s not the usual trip to see my plastic surgeon.”

Parton said she needs time to “get show ready” to be back on stage and put on a performance that fans “deserve to see.” She also tried to ease any concern that her situation is serious. “Don’t worry about me quittin’ the business because God hasn’t said anything about stopping yet,” she continued. “But, I believe He is telling me to slow down right now so I can be ready for more big adventures in life.”

“I love you and thank you for understanding,” she signed the note. Earlier this year, Parton’s husband Carl Dean died at 82. The pair were married for nearly 60 years.

Tickets purchased for the original dates will be honored when rescheduled dates are announced. Refunds are also available.
