Shania Twain’s Husband’s A Love Cheat

People reports that Mutt was a real dog and was shagging his married secretary.

“Sources close to the situation say a third party was involved: Marie Ann Thiébaud, a longtime secretary and manager of the couple’s chateau in Switzerland. “Mutt and Marie Ann left their spouses for each other and are still in a relationship,” says one source.

Lange denies the claims. “It’s absolutely not the reason [for the separation],” the famously reclusive producer told PEOPLE when asked about the alleged affair. He also denied that he was in a romantic relationship with Thiébaud: “I’m not, no,” he said. “It’s not true.” (Thiébaud could not be reached for comment.)”

Nothing quite like shagging the hired help to bring a marriage undone.
