Dolly Parton's 'secret' husband inspired classic song but not I Will Always Love You

Dolly's relationship with Carl has always been much more private. However, she has revealed small personal details that give a beautiful glimpse into their life together.

Earlier this year, for Valentine's Day, the country star tweeted a very rare shot of them together, showing Carl kissing her. Dolly also admitted she dresses up for him at home as much as she does in public.

She said: "I like to dress up for Carl. Every day, I put on some makeup and fix my hair because I think, 'Well, the whole world, I’m out here and everybody else sees me all dressed up, and I’m not going to just kind of go home and just flop on him. Nobody wants to make out with a slouch!"

She also, famously, recreated her Playboy magazine cover for him and shared the moment with the world.
