Marie-Anne Thiébaud is going on the offensive.

The woman accused of having an affair with Mutt Lange - and, subsequently, breaking up his marriage to Shania Twain - is speaking publicly for the first time about the allegations that have made her more of a public enemy than Dina Lohan.

"You cannot believe everything you read in the press," Thiébaud, ironically, said to the press.

When by People if she had an affair with Lange, Marie-Anne said: "No."

Of course, that response contradicts several sources close to the situation. They say Thiébaud and Lange left their spouses for each other and continue to maintain a romantic relationship.

So we guess it all comes down to this: Can we believe Marie-Anne Thiébaud?

As Marie-Anne Thiébaud's name has become synonymous with "dirty, lying adulterer," the former secretary for Shania Twain and Mutt Lange has finally spoken out.

Thiébaud was contacted E! News at her home and told the celebrity gossip network:

"I know what you're ringing to ask me about. But, when marriages break up they break up for all sorts of complicated reasons, it's never just one reason. And those reasons should be kept private. If you're looking for a person that broke up a marriage then you have the wrong person. I'm not that person."

Thiébaud declined to comment any further on the rumors, asking that the press not "intrude into people's private lives."

Good luck getting that wish to come true, Marie-Anne Thiébaud.

Man, Shania Twain feels scorned by a woman.

Not only must the award-winning country singer deal with the divorce from her husband of 14 years, but reports have surfaced that the reason for the break-up between Twain and Mutt Lange is his affair with Marie-Anne Thiébaud, a former close friend of Shania.

Pictured on the right, Marie-Anne Thiébaud served as a secretary and house manager at Twain and Lange's estate in Switzerland for many years before deciding to allegedly get it on with the man called Mutt.

Christiane Plante would be proud.

Marie-Anne Thiébaud reportedly screwed over Shania Twain by screwing her husband.

According to a source, Lange, Twain and Thiebaud "would vacation and spend holidays together... Shania considered Marie-Anne one of her best friends."

This insider added that Shania is "devastated" by her split from Lange, but allow us to assure her: if this news is true, Shania, you're much better off without that cheating loser.

There's no denying the fact that the 14-year marriage between Robert "Mutt" Lange and Shania Twain is over.

But there is controversy over the reasons behind the split.

Self-absorbed gossip blogger Perez Hilton reports that Lange had an affair with Marie Ann Thiébaud, a longtime secretary and manager of the couple's chateau in Switzerland.

This dude cheated on Shania Twain. Really?!? We hope Marie Ann Thiébaud was worth it, Mutt.

"Mutt and Marie Ann left their spouses for each other and are still in a relationship," a source said, though Lange denied this allegation.

"It's absolutely not the reason [for the split]," he said.

Notice that Mutt - if that is his real name! - didn't deny sleeping with Marie Ann Thiébaud, though.

This story causes us to question the sincerity of Twain's classic song, "You're Still the One."

Looks like these two haven't made it, after all. They may have taken the long way, but is this really where they hoped to get to someday?
