The one-hour special, which premiered in Britain last November, will look at the Scottish singer's rocky road to stardom after reaching worldwide fame on Britain's Got Talent. Boyle discusses everything from losing the reality competition to numerous media reports about her meltdowns and bad temper.
"This unlikely superstar has had to put up with people calling her mad, stupid and backward since she first burst to fame 18 months ago," Morgan said in a statement. "To all those who vilified her, I simply command you to watch our encounter, and see for yourself the intelligent, eloquent, passionate and incredibly endearing woman that I've always said she is."
Boyle was admitted to The Priory, a psychiatric clinic in London, the day after losing Britain's Got Talent, and reportedly exhibited erratic behavior after failing to win the title.
She has since released two albums: I Dreamed a Dream, the second best-selling album of 2009, and her recent Christmas record, The Gift. She is also nominated for a 2011 Grammy award for best pop vocal album.
Morgan will launch a nightly CNN show, Piers Morgan Tonight, on Jan. 17.
Piers Morgan's Life Stories will air Monday, Jan. 10 at 8/7c on TV Guide Network.
