Dolly Parton believes her marriage has lasted so long because her husband Carl Dean isn't famous.
Dolly Parton doesn't believe celebrity marriages last.
The '9 To 5' singer claims her 44-year union with spouse Carl Dean works so well because he stays out of the spotlight and they never need to compete with one another.
She said: "There are so many break-ups that the names pass me by but it makes me think, if you want to escape the spotlight why marry another famous person? It's never going to work.
"You're either in competition or your priorities are different. Your schedules will always clash so you'll never see each other.
"My husband is a homebody and has nothing to do with the celebrity world. We've been married 44 years and have worked so well together because we're not in the same business."
Dolly admits she doesn't think she and Carl would still be together if he had tried to embark on a career in showbusiness.
She added: "I met my husband before I became a star and he doesn't care about any of it.
"If I'd married someone in the same business, it would never have lasted.
"Even though he's intrigued by showbusiness, he'd never want to be in it."
