Dolly Parton and Carl Dean

The ‘I Will Always Love You’ singer has been married to her elusive husband Carl, 81, since 1966.

Dolly, 77, believes they are still happily married because she doesn't drag him around on her tours.

She told People magazine: "He’s always supporting me as long as I don’t try to drag him in on it. He’s always been my biggest fan behind the scenes … But anyway, he’d never come dragging around. I’d rather bring somebody else with me, you know? He’s never jealous of that either."
