In conjunction with the release of her cover of "I Will Always Love You," singer Gabby Barrett hopped on a video chat with Dolly Parton recently to talk life, love and all things music.

When she wasn't picking Parton's brain for professional tips, Barrett asked the legend for advice on maintaining a happy, long-lasting marriage.

Parton said she and her husband, Carl Dean, have been going strong for 54 years, in part because they have a respect for each other's differences.

"He's pretty much a loner and a homebody, and I'm a gypsy. But when I'm home, I love that," she explained. "We don't do the same thing so it gives us different stuff to talk about. 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."

Parton added that she and Dean have "never fought," but that doesn't mean maintaining a good relationship comes easily all the time.

"You have to work at anything. Marriage is a business, too, and you got to look at it like that," she said. "You got to make the right decisions for all the little things that come up."

Last year, Barrett married fellow country singer Cade Foehner. She is currently expecting their first child, a baby girl.
