But the country music maestro hung up her cowboy boots and mini-skirts for a look many of her fans were not prepared for.
Shania updated her Instagram with a photo to promote her latest podcast episode and left fans doing a double-take.
WATCH: Shania Twain wows in a green bikini and cover-up on vacation
In the photo, the star was flanked by a group of Canadian Mounties and she was standing proudly in the middle of them.
She covered up in skinny black jeans and a navy, short coat but couldn't resist a touch of glamour as she teamed her ensemble with a pair of high-heeled boots.
Shania was beaming in the photo and still managed to look sensational in her casual attire.
Shania was promoting her Podcast
The Canadian singer captioned the post: "Poutine, ice hockey and some of the greatest music artists of all time - on the latest episode of #HomeNowRadio I'm celebrating my homeland Canada. Listen now, only on @applemusic."
Her fans flooded the comments with heart emojis and told her how much they loved her.
Shania's look was in stark contrast to her appearance in a social media post just a few days earlier.
The mother-of-one shared a selection of looks from her past concerts in a collage, which included her dressed in a white bodysuit teamed with a glitzy white wrap dress and boots.
Other looks included a sparkly pink mini dress with thigh-high heels, and a metallic blue gown.
Shania shared the collage alongside an exciting announcement, as she revealed new details of her Let's Go! residency.
She wrote: "Vegas, are you ready to have some more fun? I'm SO excited to be coming back to @zappostheater for my Let's Go! residency!! Tickets available now (link in bio)."
