Shania Twain has decided she’s due for a victory lap, and she’s taking one this summer.

Her “Rock This Country” tour, which starts on June 5 in Seattle, will be her first in North American tour in more than 10 years.

It’s also going to be her last.

“This is a very, very important time in my life on the road,” Twain said in an interview Wednesday with “Good Morning America’s” Robin Roberts. “This is going to be a big, big tour for me because it’s going to be my last.” Twain, 49, is calling the tour a “celebration.”

Twain brought country to pop music — something that’s still a challenge for contemporary female country artists — and basically provided the template for Taylor Swift’s career. Swift signaled in 2012 with “Red” that she was going to walk away from country, a decision she reaffirmed last year when she moved from Nashville to New York. Twain, her inspiration, offered her full-throated support, while others dinged Swift for turning her back on her country roots.

“I think that everybody should just follow their heart and do their artistic best, and just enjoy their creativity,” Twain told ET Canada last year. “(Swift)’s a singer-songwriter-performer, she does it all … the world is her oyster. She’s young and she needs to just do whatever she’s having fun at, and I think everybody’s loving it.”
