As soon as Shania Twain and husband of fourteen years Robert ‘Mutt’ Lange split up, rumors of his infidelity ran rampant.

The world wondered, who on earth could possibly take a man from the beautiful and talented Shania Twain? Sadly for Shania, it was good friend and employee, Marie-Anne Thiébaud . . . who is hardly all that.

Marie-Anne, 37, worked for Twain, 42, and Lange, 59, at their estate in Switzerland as a secretary and house manager. She had a husband – whom she left to be with Mutt. The two couples were reportedly close and even went on vacations together, so this was a huge surprise to everyone involved.

A source says the cheating couple are still seeing each other, regardless of Mutt telling the media the rumors are not true. “Mutt and Marie-Anne left their spouses for each other and are still in a relationship,” the source confirmed. “Their two families would vacation and spend holidays together. Shania considered Marie-Anne one of her best friends.”

Shania (or her rep) has yet to speak on the matter and is spending time with friends and family in Canada. Understandably, she is said to be completely devastated.

Poor Shania! What a d*ckhead! And the friend too. What a complete betrayal!

Yeah, I’d be in Canada too, sharpening my knives, bitches!

Shania Twain, 42, and producer husband, Mutt Lange, 59, have separated after 14 years of marriage.

It’s been rumored for years that the couple have been struggling to stay together but it seems their time has finally come to an end.

Twain’s spokesperson stated, “Shania Twain and her husband, music producer Robert ‘Mutt’ Lange, are separating after 14 years of marriage. This is a private matter and there will be no further comment at this time.”

The couple have a six-year old son together.

Shania has managed to stay out of the spotlight for the past 5-6 years, putting family in front of her career. It’ll be interesting to see if she makes a comeback!
