Former model and talk-show host Alana Stewart, 67, has just published a new memoir, "Rearview Mirror." Stewart, who was married to actor George Hamilton and singer Rod Stewart, both of whom she later divorced, describes a childhood in poverty in Texas, her life-changing move to New York and California to model, and her close friendship with the late Farrah Fawcett.
But she opens her memoir with a traumatic event that happened to her at 18. Stewart tells Matt Lauer of "Today" why she chose that particular story to start the book, and what she regrets about motherhood. Watch the video above for more.
