Dolly Parton shared an update on her health after canceling her six-date residency, Dolly: Live in Las Vegas, at Caesars Palace's Colosseum. The 80-year-old country legend admitted she's 'always had problems with my kidney stones' but for the past three years her immune system and digestive system 'got all out of whack' and now need to be 'rebuilt and strengthened.' #dollyparton #celebrity #news #lasvegas
