Camille Gottlieb
Camille Marie Kelly (born July 15, 1998) is the third child of HSH Princess Stéphanie of Monaco. She was born in 1998, to Princess Stéphanie and, allegedly, her former bodyguard Jean Raymond Gottlieb. Her paternity has never been publicly confirmed by the Palace or the Princess nor have they denied that Gottlieb is her father.
She has two half-siblings, half-sister Pauline, and half-brother Louis, both from Stéphanie's marriage to Daniel Ducruet.
Because she was born out of wedlock, and has not been subsequently legitimized by any marriage between her parents (as in the case of the Ducruet siblings), Camille is not in the line of succession to the Monegasque Throne.
Her maternal grandparents were the late Prince Rainier III of Monaco and Princess Grace of Monaco (formerly Grace Patricia Kelly, an American film star).
