Arianna appeared on "Piers Morgan Tonight" with "The View's" Barbara Walters on Wednesday evening to share their memories of writer-director Nora Ephron, who died on Tuesday.
"She was a champion of women," Arianna said of Ephron, who was a HuffPost Editor at Large. "She really believed that women could do anything at any time."
Both Arianna and Walters spoke of Ephron's thoughtfulness and wit. Having known about her illness for six years, Ephron "wrote in a funny way, but a touching way, about death," Walters remembered.
"She did write a lot about death for somebody who was so funny and so full of life," Arianna added. "Part of it was her sense that you should live every day as if it was your last day. She even said, 'You should eat your last meal every day, because when the time comes to eat your last meal, you'll probably not be feeling like it.'"
At which point, Walters jumped in: "And, by the way, she was a great cook!"
