If you want to fast-track yourself to duet paradise, all you need to do is find a tune featuring Dolly Parton and Kenny Rogers. The famous country music collaborators have a lot in common: Incredible voices, southern roots, and septuagenarian status, to name a few shared traits.

So it's no surprise that we've had a hard time believing the two when they swear they're "only good friends." On the TODAY show Wednesday, October 25th, however, Rogers and Parton set out to debunk the rumors that they were ever an item—for good.

"First of all, she's hard to look at for me,'' Rogers quipped, in his kind-hearted drone.

"I'm not his type,'' Parton said. Rogers added, "I'm a believer that tension is better if you keep it than if you satisfy it." Then, Rogers continues: "And then secondly, she said no to me."

"Nah. You know what, we were almost like brother and sister,'' Parton commented. "And it would almost be like incest. So we just never went there." Both, indeed, are happily married to other people, Parton wed to Carl Thomas Dean, and Rogers to Wanda Miller.
