"I cheated," she tells Oprah on the episode, airing Feb. 25. "He claims to this day that I cheated first, but I don't know. I don't know about the timing." Bertinelli, 47, who's promoting her tell-all book, Losing It: And Gaining My Life Back One Pound at a Time, also reveals that her ex, with whom she's now friendly, wanted to take their relationship slow at least at first. "He didn't want to sleep with you," asked Winfrey. Responded Bertinelli: "I know ... I wanted to sleep with him ... and he wanted to talk to my dad first."
