Country singer Shania Twain's estranged husband has given his blessing to her rumored new romance with his alleged mistress' ex. Twain split from husband Mutt Lange in May, after discovering he was romancing the couple's longtime secretary Marie-Anne Thiebaud, the manager of their Swiss estate.

Thiebaud's husband, Frederick, joined the country star for a trip to New York last week, sparking reports the two hurt exes have formed a special friendship.

And Lange insists he's not bothered by reports of their alleged romance.

When asked if he was upset to see his Twain stepping out with his love rival he tells the National Enquirer, "Not at all. He's a great guy. I have no idea that is even the case. They are very good friends anyway. I wouldn't mind if it was the case they were dating, not at all."

Adding of his plans to marry Marie-Anne, Lange adds, "It isn't even that. The whole story was just a story as we are just friends in the same way Shania and Fred are. Shania didn't name Marie-Anne as the third party in the divorce. She did not."
