Report: Mutt Lange Cheated with Marie Ann Thiébaud

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.

Mutt Lange

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?

    Well.. I'd like to say just Robert Mutt is a big idiot. It's not easy to find a woman like Shania Twain these days. Besides being a pretty woman she's a big mother and deeply talented. I am a brazilian fan of Shania Twain and I'm always updated about her news, her hits etc. So, I can say that I am as devasted as her about this awful news. I just hope that Marie Ann is worth because is not that easy to replace Shania at all.Being a strong woman like Shania is, I know she will get over this pretty s

  2. Valeria Says:

    What a jackass! They have a 6 year-old son together. Wish people would realize that portion of their 'marital' commitment is the most important. Did you 'grow apart' from your son too?? Shania deserved much better than this jerk.

  3. Kari Parkinson Says:

    WOW, I can't believe Shania was with that guy, he She is a great woman and still so very young, I know she will do better~

  4. vivian Says:

    Mutt Lange is not exactly Brad Pritt, ok? So Shania you can do better than this guy, no matter that you were married to him for so many years. He did this, this betrayal, he's not worth it, move on. He is old, and really quite ugly, so sorry to say that, but the truth is the truth. The other woman, she's with him for the money and the lifestyle, make no mistake about it.

  5. S. Sweeney Says:

    Lets see some pictures of the home wrecker.

  6. BLH Says:

    Shania's Canada's sweetheart. Marriage is taken a bit more seriously here. Shania will meet someone who deserves her and is not going to desert her and her son when he thinks he sees something better. Hope this Marie Ann is proud of herself. But, really, Mutt is looking a bit old and Shania - well, that Canadian air, she still just as beautiful as the day they were married.

  7. jacky Says:

    I am disgusted with Mutt. Makes me not want to get married, What more does he want?? He has ruined all the lives around him and I hope Marie Ann is happy that her and Mutt have also ruined the family life of their son now. How can she work for Shania and betray her like that? In their home! Shania doesn't need this. she has stayed out of the tabloids and has been through enough hurt in her life. MUTT ...BIG DOG.

  8. jade Says:

    I am sorry to hear this about Shania, and her husband. It's really disheartening when you think that a celeb couple have finally gotten it right. You hear what a dog their husbands really are.Typical male even if you have a super model looking wife like Shania Twain, who you raised a son with your looking else where, well shame on you Mutt Lange, I hope you are happy with the bed you made now.

  9. Melissa Says:

    Wow, her husband is such an idiot in this planet! He is going to loose that beautiful woman that he cannot find another for the rest of his life. There is a lot of beauitful ladies but it is not the same as Shaina. Shaina deserves something better and Im sure there is a man who loves her more and wanted to be treated her a princess.

    MATT, enjoy your new bed but that lady, Marie Ann doesn't last long. Remember this because I know it is going to happen. Watch her, why she acts so easy to spread her legs to let your "down there" to crawl in?! Have a good journey Mutt-hole,

  10. Charlie Says:

    Ever stop and think that he left because something just wasnt right? If the guy was happy, he'd still be there!! as for shania, well she definately looks hot but she wouldnt be famous only for mutt. how do everyone think he got her in the 1st place? A young, pretty but non popular singer meets the ugly , older but rich as hell producer!! He wanted her in the sack and she wanted popularity! They both got what they wanted. Leave the guy alone. She got the better deal. Now thanks to him, she is also rich and famous...

  11. Mae Says:

    What a shame! She seemed so happy with Mutt!
    some men are so dumb! I am sure he will regret
    this in time to come! Ann Marie is not that pretty
    two Mutts together! Some guys just want it all!
    Cake and eat it too! Shame on you Anne Marie!
    Shania has been thru enough already!
    I am sure a LOT of men will be in line for Shania!! When the novelty wears off with this
    woman, I bet he will be kicking his ass!
    Move on Shania! We love you!!

  12. marilyn Says:

    i am so sad about this what a dog (no wonder his name is mutt)

  13. Debbie Says:

    To Charlie who says something just wasnt right? Poor mutt wasnt happy, well BS, if that is the case then either work harder on the marriage or end it. There no sense in cheating. As for Mutt making Shania rich and famous, her time would have came with or without Mutt. No doubt he has gotten a nice share of money by so called making her what she is. Mutt I hope you marry this home wrecker and she takes you for a bundle.

  14. rere Says:

    I saw the secretary picture hahahaha it's like choosing the beast over the beauty, we love you Shania....you'll have someone you really deserve instead of this jackass!!

  15. Robert Says:

    I'm glad that Mutt has finally come to his senses and dumped that chick singer. He can do a lot better than her.

  16. John Says:

    Couple of thoughts here. #1. It doesn't take a Brain Surgeon, to see what BOTH of them saw in each other! He saw her looks and smoking-hot body! She saw $$$$! Pure and simple! Talk all the B.S. about they loved each other, if you want to. If you believe that, I got some really nice swamp land I wanna sell you.
    It's funny you never see a woman, who looks like her, marrying a Ditch Digger! And you never see a man with his money, marrying a 300lb Maid!
    He's old enough to be her DAMN DAD! He got what he wanted and she got what she wanted. Time to go their merry ways!

  17. JoJo Brown Says:

    Wow...such a brain drain figuring this one out huh? How does a guy "cheat" on one of the most beautiful women in the world? Perhaps she REFUSED to GIVE IT UP!?! Hello??? Men dont STRAY if they are getting what they need AT HOME...PERIOD. Shania is clearly FRIGID. Hot as he!! and COLD AS ICE! He saw someone who was probably interested in him and he went for it. It doesnt take EINSTEIN to figure out he WASNT getting it from wifey poo. Duh. He will now have to "SUFFER" with his mega millions as a bachelor...LOL! Times are hard.

  18. Andrew Says:

    All these women blaming Mutt for cheating...what a joke! Maybe Shania was not giving him what he needed in the relationship and he wondered off into the arms of a women that cared. You go get em Mutt and get what you deserve, life is to short to deal with women that think they deserve everything and give nothing.

  19. Hot_blond Says:

    Oh, please. All these people who proclaim Shania was "frigid" or "wasn't giving it up" and she CAUSED the infidelity are laughable. Some people are just serial cheaters. They could be married to someone who looks like Shania and gives it up every night, yet they still aren't happy. Mutt could just be a Mutt and he could want some strange.

    None of us knows the real situation, but we do know these are people who are BOTH MARRIED and they are BOTH leaving their spouses as a result of their affair. That's just sleazy, any way you look at it. If you are "unhappy" in the marriage, and you have no interest in working on the marriage, just be honest with your partner and leave.

    "who's bed has your boot's been under"....premonition,or just lyrics?

  21. LILA SADAFI Says:

    Dear Shania: Go to spa ,Mutt who?

  22. Bob Lange Says:

    I bet Shania's a bad lay. That hussy couldn't please an ugly guy and she had bad tits.

  23. liza Says:

    He really IS a MUTT! And the other woman is ugly, both inside and out!

  24. Sovoya Jackson Says:

    What do you all mean that Mutt "made" Shania what she is. She sure as hell paid her dues the hard way. Sure, he was an awesome producer. But remember, it wasn't just her looks that got his attention: It was her VOICE and the SONGS she sung for him over the phone as they became acquainted...yes, the songs that SHE wrote. Sooner or later, any good producer worth his salt would've hooked up with Shania professionally and her chance to make it would've come. Personally, had it been me, I would've had fun with the ugly weirdo, recorded killer songs, traveled the world and said "See ya babe, that's show business." But obviously she loved him. C'mon:14 years! That's not a golddigger. She earned her way. Period. And yes, now she will go on to make more great songs. May I suggest Tina Turner's producer.

  25. jason stratton Says:

    Well i guess he cheated on her, i dont blame him.Rumor has it that Shania does not like sex! Mutt is only human and when you are married to a hot women like Shania and she does not give it up well its like being a 7 year old kid with 20 dollars in your hand in a candy shop and your told no you cant have any of that. WOW talk about having blue gum balls!
