Dolly Parton’s family has asked fans to keep the 79-year-old country music icon in their prayers following recent health challenges. The appeal comes after Dolly postponed her Las Vegas residency on doctors’ advice to undergo medical procedures. Her sister, Freida Parton, shared an emotional note on Facebook: “Last night, I was up all night praying for my sister, Dolly… Many of you know she hasn’t been feeling her best lately.” While no medical specifics were disclosed, the message came shortly after Dolly revealed she’d been sidelined by a kidney stone that caused an infection, keeping her from attending a Dollywood event.
