Dolly Parton has denied longtime rumors that she is secretly gay.

The 66-year-old Parton, known as the Queen of Country Music, is promoting her memoir Dream More.

In an interview with Nightline, Parton, who has been married to Carl Dean for 46 years, discussed rumors she is romantically involved with childhood friend Judy Ogle. Oprah Winfrey has also long been accused of having a lesbian relationship with her best friend, CBS This Morning co-host Gayle King.

“Like Gayle, her friend, Judy, my friend, they just think that you just can't be that close to somebody,” Parton said. “Judy and I have been best friends since we were like in the third and fourth grade … We still just have a great friendship and relationship and I love her as much as I love anybody in the whole world, but we're not romantically involved.”

Parton added that when she started “Gay Day” at her theme park, Dollywood, in Pigeon Forge, Tennessee, she got threats from the Ku Klux Klan.

“When it first started there were people giving us threats, I still get threats,” she said. “But like I said, I'm in business. I just don't feel like I have to explain myself. I love everybody.” (The video is embedded on this page. Visit our video library for more videos.)
