Country music icon Dolly Parton was forced to miss a major Dollywood event Friday after her doctor advised her to stay in Nashville because of continued "health issues."The 80-year-old "9 to 5" singer was expected to appear in person at the Tennessee theme park for the opening of its new NightFlight Expedition roller coaster, but she ultimately joined the celebration virtually after her doctor told her not to travel."I’m still in Nashville, and I’m sorry about that," Parton told the crowd during a video appearance at the event, according to video shared by the Knoxville News Sentinel.DOLLY PARTON'S SISTER OFFERS HEALTH UPDATE ON COUNTRY ICON AFTER FANS WORRY OVER HER CALL FOR PRAYERS"I’m supposed to be there in person, like we planned," she continued.

"And, of course I can't be dizzy, carrying around banjos, guitars, and such on five-inch heels... not to mention all those heavy rhinestone outfits, the big hair, my big personality."Parton has previously discussed problems involving kidney stones, while also saying her immune and digestive systems had gotten "out of whack" and were being treated. She has repeatedly emphasized that she is improving."I have great doctors, and I'm doing really well, and they assure me that everything I have is treatable," she said. "So I'm going with that, and I just want you to know I thank you for standing by me and that I will always love you."
