In less than two years, Betty White has seen the passing of her 'Golden Girls' castmates Estelle Getty, Bea Arthur and Rue McClanahan. Now, the comedy icon has given her first reaction to McClanahan's death today from a stroke.

"Rue was a close and dear friend," she tells 'The Insider.' "I treasure our relationship. It hurts more than I ever thought it would, if that's even possible."

From 1985 to 1992, White and McClanahan played unlikely friends on the hit series -- White, as simple Rose, and Rue as the bodacious Blanche. Both actresses portrayed these same characters on four different sitcoms -- 'The Golden Girls,' 'The Golden Palace,' 'Nurses' and 'Empty Nest.'
