EXCLUSIVE: Shania Twain Tears Up Over Farewell Tour, Reveals New Album Details, and Goes Blonde: 'I'm Having M

It's the end of an era for Shania Twain.

Following a wildly successful run in Las Vegas, the 49-year-old country icon is gearing up to take her show on the road for the first time in 11 years -- and, sadly for fans, also the last time of her career.

"I thought that [Vegas] was going to be my last time doing a concert production environment," Twain admits in an exclusive sit-down with Entertainment Tonight. "I didn't say anything publicly, I didn't tell anybody around me, but in my mind I was thinking, 'This will be it.'"

Fighting back tears, Twain says that she felt an undeniable pull to do right by her fans and say a proper goodbye with the "Rock This Country" tour. 

"I realized that static environment, as exciting as it was, was no way to say goodbye," she admits, "and going to the fans and bringing myself to them seemed the right way to do that. So that is why I'm going on this tour."

Twain says to expect "a rollercoaster energy power show" this time around, featuring amped-up guitars, punched-up pyrotechnics, and a fireworks-worthy light show. "It's rock 'n' roll," she declares.

She'll also be rocking a new, very blonde 'do. ET's own Cameron Mathison couldn't hold back the obvious question: Do blondes really have more fun?

"Well, I'm having more fun now than ever. So yeah, I guess technically you could say that's true," she responds, teasing: "I may never quit being blonde!"

While Twain is closing the curtain on her touring life, fans mourning the end of her career can dry their tears. "I've got lots of records to make, I've got lots of singing to still do, but just the touring end of it is something I want to move on from," she explains. "I realized that I can't make records and tour at the same time."

And those new records may be coming sooner than we think. Just months before blowing out the candles on her 50th birthday, Twain reveals her wish for the next year.

"I wanna be 50 and have new music out," she says. "Whether it'll be the whole album or just a single or whatever, it doesn't matter as long as I've got something to share with the fans... that is my gift goal to myself."

After struggling through a very public divorce and nearly losing her voice, Twain says her new music is "very emotional for me, in a good way. It's been very therapeutic." Especially, she says, after fighting a mysterious voice-box issue nearly a decade ago.

"There were several years where I really thought I would never sing again," she recalls. "I couldn't vocalize properly, I couldn't get the right tone, it was tough. And then I just decided that it was time for a challenge, time to try again... After my divorce, I just felt that I lost so much, I had to try and get something back that I could maybe do, that I could maybe control.

"It was this desperate state, and so I was determined," she confesses.

It's safe to say that determination paid off. While Twain reluctantly acknowledges praise from those closest to her, saying that her voice has never sounded better, the star has her sights set on a new album.

"Now I've got probably a couple albums' worth of songs out," she says. "I've got more songs than I need for this next album."

Twain may be writing solo these days, but don't rule out duets! After learning of Nick Jonas' early schoolboy crush on her, Twain says she would "absolutely" love to work with him in the studio. Also on her wish list: Sia. "I would love to sing with her," Twain says.

In the meantime, Twain's "Rock This Country" tour kicks off on Friday in Seattle, Wash., and will roll through the North America, wrapping in Toronto on Oct. 11. (See a full list of dates below.) For more from ET's interview with Twain, tune in to Entertainment Tonight on Thursday.
