Grace Kelly was born on November 12, 1929 in Philadelphia. Daughter of an American entrepreneur and sportsman, she was raised in a conservative atmosphere that pushed her to give the best of herself. Against the advice of her parents, she decided to launch herself into acting and became a model to finance her acting classes. The actor Gary Cooper spotted her and imposed her in 1952 in The Train Whistle Three Times. The following year, the sublime blonde turns the very Hollywood Mogambo in the African savannah alongside the legends Clark Gable and Ava Gardner. Grace and Ava immediately became accomplices and the two young women spent the free evenings of the shooting to party. Grace went on to make a string of Hitchcock films and starred in The Hand in the Snare and The Crime Was Almost Perfect. The young woman thus acquired her reputation as a cold and fatal blonde. She won the Oscar for best actress in 1955 for A Girl from the Province.
Meanwhile, in Monaco, the billionaire Aristotle Onassis (future husband of Jackie Kennedy) persuades Prince Rainier that he must marry a Hollywood star if he wants to strengthen the prestige of the principality, relax the French supervision and develop tourism. Onassis considered Marilyn, but Rainier and Grace met during a photo session at the royal palace during the 1955 Cannes Film Festival. The couple announced their engagement on January 6, 1956. Grace agrees to leave the cinema, at 27 years, but will remain close to his former partners of the big screen. Thus, Frank Sinatra, to whom she had given the line in High Society, will become the godfather of his daughter Stephanie of Monaco. The wedding of the century took place on April 18, 1956 and was filmed by the MGM film company. The eyes of the world are riveted on the splendid dress of Grace. Three children were born from this union: Caroline, Albert and Stephanie. Nostalgic for the cinema, the princess fulfilled her duties perfectly and raised her children. She met a tragic end and died on September 13, 1982 while driving her Rover 3500S V8 with her daughter Stephanie, then 17 years old.
Olivier Dahan pays tribute to the life of the most elegant blonde in his 2014 biopic Grace of Monaco. Focusing on the year 1962, he plays a woman torn. The Rainier family boycotted the film, which they deemed too fictional.
