The 'Still The One' singer is planning to reveal everything about her incredible life including details of the affair her husband Robert 'Mutt' Lange had with her friend Marie Anne Thiebaud which ultimately ended their 14-year marriage in May 2008.
Shania said: "There have been moments in my life I was concerned by the reality that tomorrow would never come. Recently I experienced one of those moments to an intensity that brought on a sudden urgency to document my life before I ran out of time, before I had the opportunity to share an honest and complete account of my life, in my own words.
"There are times in your life that are meant for reflection, and this was one of them. I began writing this book with a sincere respect for the past, present and future as something never to be taken for granted."
Shania – who is currently dating Marie-Anne’s former husband Frederic Thiebaud – will also write about her childhood in Canada and her stratospheric rise to fame as a country singer.
Judith Curr, of publishers Atria Books, revealed 45-year-old Shania is hoping to inspire people with her writing.
She said: “The book will be a help and inspiration to many, and those who think they know her from her music will be surprised at the raw and personal place she writes from."
