Eartha Kitt, the actress known for her role as Catwoman and singer known for "Santa Baby" has passed away at the age of 81. Called the "most exciting woman in the world" by Orson Welles (whom we recently saw on What's My Line?) she was known for her sultriness, as well as for being controversial at times. She was still at work very close to her death and won Emmys both this year and last year for her role as Yzma in Disney Channel's The Emperor's New School.
Eartha appeared as a mystery guest on three episodes of What's My Line? -- Episode #209 of May 30, 1954, Episode #472 of July 12, 1959 and Episode #574 of July 23, 1961.
