Frederic Nicolas Thiebaud has been a true gift to me as a compassionate, understanding friend and over time, an amazing love has blossomed from this precious friendship. Fred and I are happy to announce, our ENGAGEMENT! (sic)"
Shania was previously married to Robert 'Mutt' Lange but their 14-year union ended in May 2008 after he embarked on a relationship her friend and Frederic's ex-wife Marie-Anne Thiebaud and she has said that experience has shown her who her true friends really are.
Shania - who has a nine-year-old son, Eja, with her ex - said: "In the last two and a half years of adjusting to life after separation and divorce, I needed to lean on others more often than I was accustomed to. These people have been gifts, and I am fortunate to have so many of these beautiful people - friends, family and beloved fans, who's support I cherish more deeply with each day that passes. Now another year is about to pass, and I would like to thank everyone who helped me believe that new beginnings are possible and that love can be trusted."
