Shania Twain is reflecting on her relationship with her ex-husband Robert "Mutt" Lange.

Twain, 56, shared what it was like to learn about her ex-husband’s affair in her new Netflix documentary "Not Just a Girl."

"It was similarly intense to losing my parents," she said in the documentary’s trailer. "I thought I had lost my voice forever. I thought that was it."

In 2008, after 15 years of marriage, Twain learned that Lange, 73, was having an affair with her then-close friend and personal assistant Marie-Anne Thiebaud. 

Twain and Lange’s divorce was finalized in 2010.

Grange was a record producer, and he co-wrote and produced several songs for Twain. Some of those include: "That Don’t Impress Me Much," "Any Man of Mine" and "You’re Still the One."
