Grace Kelly’s ‘wild child’ daughter, Princess Stéphanie of Monaco, once ran away with the circus after falling for an elephant trainer

According to Rippon, "love blossomed" between the princess, who was 36 at the time, and elephant trainer Franco Knie after they met at Monaco's annual International Circus Festival in 1999."She literally went off and joined the circus, she and her kids," Bidisha SK Mamata, a British filmmaker, and journalist who began covering royals after making several Princess Diana documentaries, said in the film.
