Shania Twain has sold more than 85 million albums with an output that includes four studio albums and a greatest hits disc. And even though the singer has recorded the occasional holiday tune, including a duet of "White Christmas" with Michael Bublé, one thing she has yet to do is release an collection of Christmas tunes.

While she has been focused most recently on her upcoming Las Vegas concert series, "Still the One," Shania hints a Yuletide offering could soon be on its way.

"I'm more inclined to make my next record a Christmas album," she tells Up! magazine. "I've been dying to do a Christmas album for so long and I think now is the best time to do that. Once the show is underway I'm just going to, no pun intended, chill and fall into one of my nostalgic modes and make a Christmas album."

Shania's most recent single, "Today Is Your Day," was released last year, but a full studio album has been put on the back burner while she focuses on her Vegas gig. "I'm concentrating on the show and not really getting any closer to recording a new album," she says, "even though I've done so much of the writing."

Shania admits she had plenty of anxiety before committing to the series of shows in Sin City, which are now less than two months away. "I feel as if I've already gone through the most nerve-wracking part of it and that was making the decision to do it," she explains. "It was a giant step for me. I'm enjoying singing again. When I think about being on stage and being like, 'Ugh, how am I going to be able to run around in high heels shoes again,' and 'Am I going to be comfortable wearing fashion clothes?' I've been so relaxed in these last years and just being in sweats. I think I'll enjoy being back with the audience, being back with the cast and the musicians and being in that environment."

Shania's "Still the One" show kicks off Dec. 1 at the Colosseum in Caesars Palace. Tickets are on sale now and can be purchased here.
