"I was in infatuation," she told Ellen DeGeneres on her daytime show Tuesday. Fisher says in her new memoir, "The Princess Diarist," that she and Ford had an affair on the set of the 1977 film. "No one told me about location rules, or lack of rules," she said. I don't even know if he did!" "I start them, but then it starts to get warm and then you have to get another one ... they have to be that sharp, sharp, cold taste."
