Beauty, elegance, and not being Audrey Hepburn made her an international star.
Her screen career was short but legendary: High Noon, The Country Girl, Dial M for Murder, Rear Window, To Catch a Thief, The Swan, and High Society. Then, at the height of her career she became a literal princess when she married Rainer III, Prince of Monaco.
As Princess of Monaco, she focused on bringing ballet, opera, fashion, and horticulture to the People of Monaco. She was also the first female board member of 20th Century Fox, an author on both poetry and horticulture, and she sought to historically restore Newport, Rhode Island.
However, tragedy struck in 1982 when she suffered a cerebral hemorrhage while driving and drove off a mountain at the age of 52.
