Affair Causes Shania Twain To Divorce Her Husband

I don't particularly love to speculate about these things, but People is running the story and they are generally an extremely reliable source.  They're claiming that Shania Twain's soon to be ex-husband, Robert Lang, was having an affair with his secretary.

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

Robert has denied that's true.

"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."

And, of course, Shania is devestated.  Who wouldn't be?

"This came out of left field ... She loved him."

For now, she has a group of close friends and family supporting her and helping her get through this.
