After the beautiful singer's husband of 14 years abruptly left her for former best friend Marie-Anne Thiebaud in May 2008, Twain began a relationship with Thiebaud's husband Frederic, and now Twain's rep has confirmed that the two are engaged!

According to Us Weekly, Thiebaud popped the question two months ago in Switzerland, and when the couple were spotted in NYC on Thursday, the Waking Up In Reno singer was rocking a three-carat, emerald-cut diamond ring worth an estimated $100,000. Umm ... best Christmas present ever!

The country songstress has expressed feelings for her new fiancé several times on her official website calling the Swiss-born Nestlé business executive "a dear friend and true gentleman", revealing, "We leaned on one another through the ups and downs, taking turns holding each other up. We've become stronger and closer through it all."

Congratulations to the lovely couple! We are thrilled to see you get the happy ending you so deserve!
