In a conversation with fellow country singer Gabby Barrett, Parton, 74, gave advice to the newlywed and expectant mother.
She shared her decades-long marriage has lasted because of “sensible separation” and their opposites-attract relationship.

The “Jolene” singer began by telling the “American Idol” alum about the “great friendship” she has with Dean, 78.
“We're both funny, and we both have a great and warped sense of humor so we've always had a good time,” she said.
“He's pretty much a loner and a homebody, and I'm a gypsy. But when I'm home, I love that. We don't do the same thing so it gives us different stuff to talk about,” Parton continued. “He doesn't get involved in my business, and I don't in his, so we have our own little world that we create for ourselves."

The “9 to 5” singer added: "I've always made jokes that the reason our marriage has lasted so long is because I stay gone. Well, there's a lot of truth in that. We're not in each other's face all the time.
“I think there's a lot to be said about having some sensible separation because you can't be with somebody 24/7, 365 and not want to smack their face now and then," Parton admitted.
The country music legend then revealed she and Dean “have never fought” and instead opt to walk away if they get “pissy” with each other, then reconvene when calm.
“Then if you get that worked out, smack him across the head,” she later joked.

“Marriage is a business too, and you got to look at it like that,” she told Barrett, 20. “You got to make the right decisions for all the little things that come up."
Parton called the first year of marriage “the hardest” because you’re still trying to figure out and learn about your partner.
"That's the year that you get the most rubbed wrong only because you're having to share space with somebody you've never had to share your space with before. Your habits are different than theirs so you got to work those little things out,” she said to Barrett, who got married to fellow “American Idol” alum Cade Foehner last year.
