Louis XV of France and Madame de Pompadour

 In 1730, a Parisian prophetess told a nine-year-old girl she would rule the heart of a king. Years later, at a masked ball, Jeanne Antoinette Poisson, dressed as a domino, danced with King Louis XV, dressed as a tree. Within weeks, the delicate beauty was maîtresse-en-titre, given the title Marquise de Pompadour. "Any man would have wanted her as his mistress," said another male admirer. The couple indulged in their love of art, furniture, and porcelain, with Madame de Pompadour arranging for her jaded royal lover small dinner parties and amateur theatricals in which she would star (of course). While watching one play, Louis XV declared, "You are the most delicious woman in France," before sweeping her out of the room.
