The Emmy-winning actress, who died in her sleep overnight at her home, played fashionable nosey neighbor Willona Woods on the hit 1970s Norman Lear sitcom. DuBois' death comes less than two months after she reunited with her Good Times castmates for ABC's Live in Front of a Studio Audience special in December. Tiffany Haddish played Willona in the ABC special. DuBois also co-wrote and sang The Jeffersons theme song, "Movin' on Up." DuBois later reprised her Willona role on The WB's The Wayans Bros. She also guested on Moesha, Home Improvement, Beverly Hills, 90210 and lent her voice to The PJs, for which she won two Emmys.
