The producer has also worked with Lady Gaga, Muse, Maroon 5, AC/DC, and more (via Country Fan Cast). He continues to work as a writer and a producer in the music business, but Lange never worked with Twain again after their divorce.

Lange cheated on Twain with her former friend and assistant Marie-Ann Thiébaud. The couple went on to get married, live together in Switzerland, and have a daughter named Johanna (via WRYK). In a shocking twist, Twain ended up getting married to Thiébaud's ex-husband Frédéric.

In a scathing interview on Watch What Happens Live with Andy Cohen, Twain referred to Marie-Ann as "the other woman," and said, "I wish I'd never met you. I think there are just some people in life you would say I wish I hadn't met that person or I would have been better off not knowing that person" (via E! News). She continued, "I can't say I would be better off [if he hadn't cheated] because I think I learned a lot from all of that. I don't regret it."

Twain and Lange had a messy divorce, but they still manage to coparent their son, the singer told the New York Post.
