Shania Twain’s husband is showering her with love on her special day!

As the “Man! I Feel Like a Woman!” singer turned 59 on Wednesday, Aug. 28, Frédéric Thiébaud, the singer’s husband of over a decade, wished her a happy birthday with a sweet tribute on Instagram.

The Swiss businessman, 54, shared a photo of the longtime couple smiling and cuddling up to each other on a boat and penned an adorable birthday message.

“Happy birthday to this amazing human being @shaniatwain 😍🥳🎈🍰,” he wrote.

In response, Twain replied with some love — in emoji form — commenting: “❤️❤️❤️.”

On her own Instagram account, the “You're Still The One” singer shared a birthday message of her own.

Alongside a compilation of clips from her Las Vegas residency, the Come on Over residency at Planet Hollywood’s Bakkt Theater — set to “Man! I Feel Like a Woman!” of course — the singer wrote, “Today is my birthday and I’m feeling like a badass queen!”

“Thank you for all the love and birthday messages, I love you guys!” she continued. “AND I can’t wait to celebrate with you all in Vegas this week 🥰 Who’s coming out to a show? Let’s go totally crazy and have a s--- kicking time!! 💥🥳.”

Twain and Thiébaud, who frequently posts tributes to the star and her career on social media, knew each other for decades before they began dating after their then-spouses — Robert "Mutt" Lange and Marie-Anne — allegedly had an affair with each other.

"I got to observe Fred going through the same thing I was and I admired how he handled it," Twain told Redbook in May 2011, just months after they tied the knot.

"That is where I fell in love with him," she added, "because he was so exemplary in every way."

Recalling the "soap opera" beginnings of the longtime couple’s relationship in 2020, Twain told AARP The Magazine, "It's twisted. But so beautifully twisted."

Also in 2020, Twain credited "faith and love" for her and the businessman’s enduring marriage.

"I'm so grateful I found the faith and courage to love again — because the last thing you want to do when you're crushed is love again," she told PEOPLE at the time. "When you have a great loss, you lose faith; you get very discouraged."

“I'm sure a lot of people say, 'I'm never going to love again. I never want to fall in love again.' Songs have been written about that,” she continued. “I'm really glad that that got turned around for me, and that's what this relationship is."
