Twain added blue jeans and white sneakers to the outfit. His blond hair was tied behind his head.

Her husband, 53, joined her at the airport for a rare appearance in search of the star.

Thiébaud wore a navy coat over a gray polo shirt and dark gray jeans. He was walking in black and white sneakers, and had a black backpack slung over his shoulders.

His curly brown hair, dyed gray at the front, touched the top of his broad shoulders.

Shania and Thiébaud tied the knot on 1-1-11 after shocking the world with their ‘husband swapping’ romance.

Shania’s marriage to her first husband, Robert John ‘Mutt’ Lange, ended after 14 years in 2008 after she discovered his affair with his long-time secretary and best friend, Marie-Anne Thiébaud.

In a rare partner exchange, Twain married Thiébaud’s ex-husband Frederic in 2011, and they are still going strong.

He reflected on his devastating split from five-time Grammy winner ‘Mutt’ in a People cover story last month.

“It was a very low period in my life,” he admitted.

But now, she really is happier than ever with Thiébaud, saying, “I really found such a wonderful life.”

Shania and Mutt’s 21-year-old son, Eja D’Angelo, is also a musician and they continue to share a recording studio.

In the interview, Shania also referred to her health problems.

The Not Just a Girl star has undergone multiple open throat surgeries and therapy for the voice disorder hoarseness, which developed after he was infected with Lyme disease in 2003.

‘I may not be able [sing] forever. And then you may have to make a decision. “Do I want to have another surgery?” what I could do,’ Shania said.

Or maybe I let other great voices sing my music and keep writing. And I will make that decision when the time comes. Right now I’m enjoying where I am.’

Twain’s sixth studio album, Queen of Me, which she wrote and recorded during the pandemic, will be released on February 3.

The Giddy Up singer will kick off her 76-date Queen of Me tour on April 15 at the Tortuga Florida Music Festival in Fort Lauderdale.
