And although the Grammy winner went ahead and recorded the tune, she didn't garner Carl's stamp of approval.

Dolly remembered: "I played it for him and he said, 'It's okay.' He said, 'Are you sure that's ‘Stairway to Heaven' or ‘Stairwell to Hell?''"

But that isn't to say the country star doesn't have other tricks up her sleeve to keep her decades-long marriage intact.

Back in October, Dolly revealed the beauty hack she's been doing for years to look her best while spending time with her husband.

"When I arrived in L.A. in the '80s," Dolly wrote in her book Behind the Seams: My Life in Rhinestones, per Insider, "I started sleeping with my makeup on, partly because of the earthquakes. I thought, 'I'm not heading out on the streets without makeup in case there are cameras out there! I'm going to be ready to go!'"

It's a rule that folded over into her marriage. As she put it: "I don't want to go to bed looking like a hag with Carl."
