She was the eldest daughter of Marshal Antoine de Gramont and Françoise Marguerite du Plessis, a niece of Cardinal Richelieu.
In 1660, Catherine married Louis de Grimaldi, the 2nd Duke of Valentinois and heir to the throne of Monaco, who is described as "a glorious and avaricious Italian". They had six children. In 1662, she became Princess of Monaco.
She visited Monaco in 1662, where she stayed for three years, after which she returned to the French court.
The Prince and Princess of Monaco spent more time in Paris than they did in Monaco. Catherine Charlotte"s beauty did not go unnoticed.
Madame de Sévigné described her as "greedy for pleasure", and she was nicknamed Catherine the Torrent. The king, who was losing interest in his mistress, Louise de la Vallière, began an affair with Catherine Charlotte that lasted only a few months.
Catherine Charlotte"s husband, Louis I, Prince of Monaco, diplomatically left court and went off to war.
In reality this was part of a plot designed by Henrietta of England to distract the king from Louise so that she might gain him back for herself. Louis XIV did in fact leave Catherine Charlotte after a few months, not to go back to Henrietta, but in favor of Madame de Montespan. Some gossip has it that, during this short affair, Catherine also had an intimate relationship with Henrietta.
She was forced to return to Monaco in 1668 after having been banished from court for her affairs
