Shania Twain kicked up her heels in a jaw-dropping outfit this week as she prepared to take the 'Legend' slot at Glastonbury music festival
The 58-year-old proved she's in incredible shape during a performance in Ireland where she showcased her flexibility for fans.
In the images she shared on Instagram, Shania wore the tiniest mini–dress and knee–high, white, cowboy boots as she rocked out for the crowds.
One photo showed Shania doing a high kick in the skintight, lycra ensemble and baring her fishnet-clad legs.
She captioned the post: "Cork… That was great craic!! (I’ve been brushing up on my Irish if you don’t know) Nothing like a sold out show to kick off the tour! And can we get a little commotion for the boots? I loved kicking about onstage in these!! Belfast tomorrow!."
Her fans said her performance was amazing and commented: "What a show," and "You look 19 omg."
Shania managed to put on a youthful display with long flowing locks, and energetic dance movies, leaving her social media followers asking "what is your secret?"
The truth is, it's a tough gig to have the energy to perform night after night and Shania admits it.
Ahead of her intense shows, she adheres to an unbelievably strict diet. "I am an athlete," she told The Sun. "I have to breathe, I have to project. I have to pace everything.
"I only drink fluids all day until after the show. I drink my food, so I blend my food. Lots of blended spinach and blueberries."
Once the shows are over, she relaxes her diet but is still healthy.
"I am vegetarian, so I only eat vegetarian proteins, but I will eat whatever. I don’t eat like a rabbit. I am happy to have pasta, and I will have a glass of champagne after the show – I like to celebrate.
"It’s got to be good quality but I’m not a snob about it."
Shania is embracing the aging process too and says she feels confident to wear her tiny on–stage attire.
"Every month or day that I may notice another sag or another bit of cellulite, I want to know it’s there. I want to be OK with it instead of thinking, I have to cover it up or not to look," she said, adding: "I have to take myself on the stage without feeling like I have to cover myself up. I want to feel liberated."
