Dean McDermott and Tori Spelling seem like the perfect couple now, but the beginning of their relationship wasn't so smooth. McDermott left his wife, Canadian television personality Mary Jo Eustace, for Spelling in 2006. Eustace decided to go public with her story and write a book called "The Other Woman." She detailed the days leading up to the split and how it felt to have her husband taken away by a movie star. —XFINITY Entertainment Staff (Photo by Frederick M. Brown/Getty Images)
