Five-time Grammy award-winner Shania Twain has been out of the public spotlight for six years. Afflicted by the pressures of her career, her perfectionism and her deteriorating self-confidence, Shania stopped performing in 2006 while, behind closed doors, her marriage to music producer "Mutt" Lange was unraveling.

In this online exclusive video, watch the first five minutes of the premiere, then tune in for the full episode, Sunday, May 8 at 11/10c on OWN.
