Monaco’s royals were out in force at the annual Rose Ball in Monte Carlo on Saturday, March 27, and for two of the royal couples, love was evidently in the air.
Prince Albert II arrived again this year with both his sister, Princess Caroline, and his longtime partner, South African swimmer Charlene Wittstock. Albert was demonstrative in his affection for Charlene, even kissing her on the cheek as they danced.
The younger generation of Monegasque royals were also in attendance at the Morrocan-themed ball, which helped to benefit the Princess Grace Fund. Pierre Casiraghi, youngest son of Princess Caroline, arrived hand-in-hand with Italian girlfriend Beatrice Borromeo. His brother and sister, Andrea and Charlotte Casiraghi, arrived together without their significant others, Tatiana Santo Domingo and Alex Dellal, though Tatiana and Alex were also spotted attending the ball. Could there be trouble in paradise for these two royal romances?
