The Monaco royal family shared an official portrait from the reception, and the photo showed that Charlotte borrowed something from her family jewels.
Charlotte wore a stunning necklace, that happens to be the same Cartier diamond tiara necklace that her grandmother had received as a wedding gift in 1956, when she married Prince Rainier III.
Her second bridal look was completed with a strapless white gown.
The newlyweds skipped the pomp of a royal wedding, by saying "I do" with a simple civil ceremony.
Charlotte’s civil ceremony marriage took place at noon inside the State Apartments and was mostly attended by family and friends.
Her entire family was present for the ceremony, as well as Prince Albert, Princess Charlene and their children, Princess Gabriella and Prince Jacques.
The couple are parents to 6-month-old son Balthazar.
This is Charlotte’s first marriage and Rassam’s second. Charlotte is also mum to 5-year-old son Raphael from a previous relationship with comedian Gad Elmaleh.
While her new husband also has a 7-year-old daughter from his previous marriage.
