Age is just a number, especially if you're Dolly Parton. The country icon turned 74 in January and she has no intention of slowing down. In fact, she said she'd love to pose for Playboy again for her next birthday.

"I don’t plan to retire. I just turned 74 and I plan to be on the cover of Playboy magazine again,” she told 60 Minutes Australia recently. “See I did Playboy magazine years ago and I thought it’d be such a hoot if they’ll go for it — I don’t know if they will — if I could be on the cover again when I’m 75.”
