When: 1979-90 Sex symbolism: One sure way to tell a true bombshell from a mere pretender is to gauge how often you see their hairstyle copied throughout the culture. Farrah Fawcett's layered, feathered look was everywhere in the late '70s, and Bo Derek''s awful plaited cornrows from the hit comedy "10" had a brief and tacky reign during the early '80s. Amazingly (for a bombshell), Derek had a stable love life -- she remained with her longtime husband John Derek from the time they got together in 1976 (when she was just 16) until his death in 1998. Despite her success being nude, Derek's other talents were considerably less well-respected. She won three Golden Raspberry awards for worst actress and was nominated for worst actress of the century in 2000.Warner Bros.
