Yes, that is a young Bardot. She was gorgeous until cigarettes and sun exposure took their toll.
Bridget Bardot did age quickly; after 35 she didn't look nearly as good as she did a few years before. During the period when she had her long light-blonde hair that was sort of poofed up on top (I think early 60s?) was when she was at her prettiest. She looked better then than in some of her very early pictures.
By the way, Jane Russell was on Larry King the other night with some other old stars talking about Marilyn Monroe. She looked very good for her age. She struck me as a strong woman, while Mamie Van Doren who was also on seemed very sweet. It was an interesting show.
