Broadway star Gwen Verdon had one number as a hotel maid, but her sexy moves were deemed obscene. She was cut, although her name appears in some cast lists, and her scene re-shot with a non-musical performer.
However, one gets a brief glimpse of Ms. Verdon as a 'flapper' at the very beginning of the brief flashback number, "Miss Annabelle Lee" (showing the 'aunts' in flashback in the 1920's).
Not actually a sequel to Gentlemen Prefer Blondes since the film is about new characters in a completely different story line.
