Not sure you can be a babe much north of 40 - witty, intelligent, lots of fun, yes - but babe means something else. I would nominate Jeanette "The Body" Mac Donald. She was in all sorts of shows as a singer and actress, raised tons of money for WW II and became a favorite of a young Ronald Reagan. She apparently slept around a lot and may have been married once, but always denied it.
I had a real pubescent thing for Mitzi Gaynor, who was in South Pacific. She stayed married to the same man till death did them part 52 years later.
Ingrid Bergman - YES. Catch her in Casablanca. You may never see Elizabeth Taylor looking better than in Butterfield 8, considered pretty trashy in 1959.
And let's not forget Lauren Bacall, only 20 when she became - er - involved with Humphrey Bogart. Sophia Lauren was a 10 before anyone ever heard of Bo Derek.
Of course, all the screen goddesses are made by a skillful Director of Photography.
