Dolly Parton has revealed that she is planning to model for Playboy magazine before she turns 75 in January.

The country music icon appeared on the cover of the men's mag in October 1978 wearing bunny ears and a shoulderless black dress, and was also subject of an in-depth interview inside.

With her milestone birthday approaching, Parton has admitted that she is discussing the idea of once again becoming a Playboy cover girl more than 50 years on.

"Yeah, I just might do it, if I can do it in good taste and they want it," she told Scott Mills on Radio 5. "We'll do it along with a really good interview inside.

"So, yeah, we've talked about it."

Parton is currently promoting her 47th solo studio album, A Holly Dolly Christmas.
