The next royal wedding is just days awaym and it turns out, when Monaco's Prince Albert told PEOPLE he was arranging a "mostly informal" affair for his nephew and the bride, he was royally understating the case.
The civil wedding service for Pierre Casiraghi and Beatrice Borromeo in Monaco – followed by a religious ceremony one week later on the Borromeo family islands in northern Italy – will be held on Saturday in the Pink Palace's Salon des Glaces, the formal gold-leafed reception room reserved for the reigning sovereign's official family functions.
The service will start at 11:30 before 70 family members and friends, and be officiated by Philippe Narmino, Monaco's Justice Minister. Narmino also conducted the civil service between Prince Albert and Princess Charlene in 2011 and registered the birth of their twins, Prince Jacques and Princess Gabriella. Princess Charlene and Prince Albert (who discreetly attended Pierre's bachelor party in Spain's Castille Requesens) will be at the civil ceremonies, as will the groom's mother, Albert's sister Princess Caroline, and members of the immediate Borromeo family.
Princess Stephanie as well as Pierre's brother Andrea and sister Charlotte are also expected.
The civil ceremony will last approximately 20 minutes, to be followed by a brief toast and a procession down a ceremonial stairwell to the Palace gardens, where the cavagnetu, an informal Monégasque garden picnic, will already be in swing. Pierre and Beatrice were greatly involved in planning the noon fete, says a source, and have arranged several surprises.
Along with roving folklore music and dance groups and the pétanque matches customary to Mediterranean summer afternoons, they've requested their expected 500-plus guests honor an usual dress code: wearing their native regional costume.
