"We are 'in talks,' so there's nothing that's been defined yet," Wynonna explained. "I just felt it in my spirit. A couple weeks ago I said, 'It's 2010. It's been 25 years. It's take your mother to work year. It just feels like it's the right time; she'll be 64 in January, and I think it's time - not the whole year, but it's just going to be a way to celebrate her."

Wynonna said she started thinking about the Judds in 2010 when the two performed at this year's CMA Music Festival in Nashville. "It was huge," she recalled. "We sang for 50,000 people, and they sang back to us, and it was a holy moment. And on the drive home I thought, 'Y'know, I really appreciate where I've come from and the people do, too, and they love the Judds' music and it hasn't disappeared.' I just thought, 'Y'know, I think it's time.' "

Wynonna said that she and her mother "are open to" recording again as the Judds as well as playing live. She also is "thinking about" asking Naomi to join her on her annual "A Classic Christmas Tour" next year. "We plan a year in advance," noted Wynonna, who kicks off this year's run Nov. 28 in Hershey, Pa.

Any Judds activity will come on top of other plans Wynonna has for the new year - including the publication of a new novel, "The Restless Heart," that's aimed at young adult readers and tells Wynonna's own story through a fictional character.

"She's basically the Miley Cyrus age group area, so I can tell my story through her about trying to make in the music business. Who can't relate to that?" Wynonna said.

Wynonna is also starting work on a follow-up to this year's covers set, "Sing: Chapter 1," but hasn't come up with a concept or direction for it yet.

"I may go traditional. I may decided to do blues. I may decide to do '80s rock," she explained. "I'm a work in progress. I don't have any single, one-line definition of where I'm at. I'm kind of all over the map right now, but we'll hone in on something very soon, I think."
