Betty White opens up to ET’s Mary Hart about the death of her beloved friend, Bea Arthur. Betty says it was difficult when she realized that her "Golden Girls" costar was nearing the end. "You have to let somebody go at that point, but it doesn't make it easy. She was really special." Betty adds: "It's like losing an era, when you lose somebody like Bea -- because she was such a special person."The 87-year-old acting legend — when asked how it feels to still be actively working -- tells Mary she considers herself "the luckiest old broad on two feet." Watch the video as Betty gives her thoughts on working with Ryan Reynolds and the "talented, beautiful, funny" Sandra Bullock. Plus, she reveals how the movie made her speak the language of the Eskimos.
