Eustace moved to Los Angeles when McDermott went south to develop his acting career. They had one child, Jack Montgomery (born October 1998) and were in the process of adopting when McDermott began his affair with Tori Spelling. Eustace later finished the adoption of her daughter Lola (born April 2005) as a single parent. McDermott later left Eustace to marry Tori Spelling and quickly became a tabloid fodder. Eustace then returned to Canada with her children, only to sometime later after 2008 move back to Los Angeles. Eustace wrote about the break-up of her marriage in the book "The Other Woman: Twenty-one Wives, Lovers, and Others Talk Openly About Sex, Deception, Love, and Betrayal".
