Parton addressed the unusual speculation with humor.
She explained that because Dean was rarely photographed or seen at public events, some people assumed he might be imaginary.
In reality, his lack of visibility reflected his personality rather than any mystery surrounding the marriage.
Parton described Dean as reserved and quiet. She believed that if he had regularly entered her public world, he would have lost the peaceful life he valued.
The country star also pointed out an important distinction between their choices. Dean had chosen to love and marry her, but he had never chosen a career in show business.
Parton respected that difference and made a point of protecting it.
