Wonderful:Dolly Parton’s confession about her 57-year marriage to Carl Dean will surprise you

Dolly Parton and her husband Carl Dean have been together for a whopping 57 years – and the secret to their happy union may just surprise you.

The 78-year-old’s husband, 81, prefers to keep himself out of the spotlight and hasn’t been pictured publicly with Dolly for decades. But keeping their relationship out of the limelight isn’t the reason for their longstanding marriage.

According to Dolly, they’ve lasted almost six decades because they don’t spend every waking minute together.

“I’m just saying, anything new gets old,” she told E! News. “And I think if you just kind of stay together so much, you just nitpick every little thing and notice all that.”

Agreeing that absence really does make the heart grow fonder, Dolly continued: “It’s worked for us because we both do different things and it’s exciting when we are together.

“So the fact that there’s some little space that makes it exciting when you go home.”

But when they spend time together, Dolly and Carl are eager to “enjoy” each other’s company.

“We just enjoy each other,” she said. “I like to cook. And one of the things that we like to do—not necessarily a date night, we have a lot of date days—we have our little RV and we like to travel around.”

She added: “Going down and get some food or I’ll make a picnic and we go down to the river and have a picnic and just kind of ride around and do our little things.”

Dolly was only 18 when she first met Carl, who was 21 at the time, outside their local laundromat in Nashville on the first day she moved to Music City in 1964.

Two years later in 1966, shortly before Dolly released her first album, they were married in Ringgold, Georgia, with only her mother there as a witness.

It was shortly after their wedding Carl made it clear to Dolly, that he had no desire to follow her into the public eye.
