And just as you'd expect, the 70-year-old knows exactly how to turn her two-bedroom, two-bathroom tour bus into a home.
"I live on my bus. I don't stay in hotels at all so I don't have the hassle of airports or going in and out of hotels," she told People.
She will be on the road, as usual, with her childhood pal, Judy Ogle, and she makes sure she brings some home-cooked meals along for the ride.
"I cook a lot of food before going and I put it in the freezer. I'll cook country things, like chicken and dumplings," she said.
But the dumplings will have to be a once-in-a-while indulgence, because Parton says she has to go low carb when she's on tour. Her show clothes are so fitted.
"There is nothing more uncomfortable than trying to wear those tight-ass clothes when you're too big for them,” Parton said. “I have to work at it ‘cause I'm a little old thing. I'm just 5'1" and I still have that country girl appetite," she admitted, "so I have to watch it."
