Debbie Reynolds was an American actress and singer married to Eddie Fisher, who left her for Elizabeth Taylor in a highly publicized 1958 scandal. Reynolds had an extensive film and TV career and famously played Bobbi Adler, Grace's eccentric mother, on the sitcom 'Will & Grace.' Liza Minnelli, Nancy Sinatra, and Judy Garland (Liza's actual mother) were not married to Eddie Fisher and didn't play this role — Judy Garland is a plausible-sounding distractor since she's also a famous singer-actress mother figure, but the Eddie Fisher marriage and Will & Grace role uniquely identify Reynolds.
