Tori Spelling accusing her mother, Hollywood socialite Candy Spelling, of cheating on her dying father in her new memoir sTori Telling, in stores now. For the first time, Tori uses the word “affair” about her mother’s relationship with family friend, Mark Nathanson, while her dad, legendary television producer, Aaron Spelling, was on his deathbed.

In July 2006, Candy, with whom Tori has always had a guarded relationship, denied the affair and said they were just friends.

“That’s her truth to tell,” Tori says. “I did resent it, but she was there for my dad. I did resent Mark’s relationship with our family. He’s no longer in our lives, including our mother’s.”
