Betty White, the quick-witted comedienne whose ribald humor as showcased on The Mary Tyler Moore Show, The Golden Girls and Hot in Cleveland made her America’s ageless darling, has died. She was 99.

The beloved five-time Emmy Award winner and animal advocate, whose career reached another level after she became an octogenarian, died overnight Thursday into Friday at her Brentwood home, her agent and close friend Jeff Witjas told The Washington Post.

“Even though Betty was about to be 100, I thought she would live forever,” Witjas said in a statement to People magazine. “I will miss her terribly and so will the animal world that she loved so much. I don’t think Betty ever feared passing because she always wanted to be with her most beloved husband Allen Ludden. She believed she would be with him again.”
