Shania Twain married hotshot producer Robert John ‘Mutt’ Lange on December 28, 1993, and she expected their marriage to end happily, just like every woman’s fantasy.

They produced lovely music together, collaborating on her best-selling album Come On Over in 1997 and generating millions.

The two met in the early 1990s when he heard her tracks on her maiden album.

Lange approached her in June 1993 and offered to produce and create songs for her future album. They married in December of that year after quickly becoming a couple.

They relocated to the tranquil Swiss town of Corseaux, which overlooks Lake Geneva, in order to avoid the famous craze, and the birth of their son Eja in 2001 only added to their delight.

Shania had also found a best friend in PA Marie-Anne Thiebaud.

The ladies had been pregnant together while living about half a mile apart, and Shania confided in Marie-Anne when her marriage was on the rocks.

But in a strange twist, Marie-Anne had been having an affair with her 15-year-husband, which she discovered the day after he filed for divorce.

According to People, Lange abruptly informed Shania in the summer of 2008 that he wanted a divorce, but he didn’t offer her a comprehensive explanation for the breakup of their 14-year marriage.

Shania sought counsel from her closest friend and aide Marie-Anne. “I said, ‘Marie-Anne, don’t you think my husband is acting strange?'” Twain told Oprah. “And she said, ‘No, I don’t see anything strange.'”

Marie-Anne was not speaking the truth, as it turned out. Lange was said to be having an affair with her.

Shania subsequently acknowledged the adultery, despite Lange’s denial, telling People that the separation was “literally just a growing apart.”

Shania Twain has described the moment she encountered ‘the other woman,’ claiming she had a panic attack when she saw Marie-Ann Thiebaud.

But it was Marie-distraught Anne’s husband, Nestle CEO Frédéric Thiébaud, who broke the news to Shania after uncovering purported proof such as phone bills and hotel receipts.

However, the vocalist of That Don’t Impress Me Much claims that the experience was a letdown since she did not communicate what she was experiencing owing to her high anxiety level.

Twain said, “I had a total panic attack. I just told her that she was a bad person – that’s all I could get out!”

‘When I left her, I thought, “You’re such a wimp, you coward!”

Thiébaud told Oprah Winfrey that he discovered unusual hotel receipts, phone bills, and even a lingerie outfit in his wife’s bag, according to the Daily Mail: “I did discover the affair with my wife and Mutt.”

“I said, ‘Guys, now you have to tell [Shania]. This is ridiculous. You just owe her that.'”

Shania said that she was stunned when she initially learned of the news: “I called [Marie-Anne] up,” she remarked on The Ellen DeGeneres Show.

“I wanted to give her the opportunity to tell me herself without me accusing her.”

Shania was so anxious to remain with Mutt that she sent her love rival a devastating message pleading for ‘mercy.’

“I am so low, so broken-hearted I can’t take it any more,” it said. “I wish you love and happiness, but I am dying, and I can’t take it any more.”

“This is killing me. Have mercy. I loved him so much, and I can’t cope any more. I don’t want life or love any more. I just want peace.”

However, in what has proven to be a “twisted” bit of irony. During their moment of need, Shania and Marie-ex-husband Anne’s leaned to each other, establishing friendship that developed into love.

In January, the pair married on a beach in Puerto Rico in a small ceremony.

‘I don’t take any day for granted any more. Fred has give me a new lease on love,’ she remarked.

Shania said that she was first hesitant to date her love rival’s ex-husband because she was “worried about what people would think of the relationship.”

Thiebaud gradually won Shania over and now refers to her as ‘Sunshine.’

Shania looked to Frédéric for comfort and support after falling in love with him. After all, they’d both gone through the same ordeal.

“We slowly became very, very good friends. We had many months of just trying to make sense of everything,” Shania told Ellen DeGeneres.

“Holding each other up was a very difficult time emotionally for both of us. And we really found something very beautiful in the end and unexpected.”

Their relationship did not begin right immediately, but Shania was pleased with Thiébaud’s handling of the controversy.

She told Redbook, “I got to observe Fred going through the same thing I was, and I admired how he handled it.  That is where I fell in love with him, because he was so exemplary in every way.”
