Charlotte Casiraghi, 32, daughter of Monaco’s Princess Caroline, will wed her film producer fiancé, Dimitri Rassam, 37, in June, according to Paris-Match.
Sources also confirmed to PEOPLE magazine that invitations to the wedding will go out in mid-May. A civil ceremony is mooted to take place between June 21 and 29 in Monaco.
The religious celebration will then reportedly take place in July at either St Remy de Province or the Mediterranean island of Pantalleria, off Sicily, where the groom’s mother, actress and model Carole Bouquet, owns a 13-acre vineyard estate.
The couple have a five-month-old son named Balthazar. Casiraghi, the eldest granddaughter of Princess Grace, has never been married. She also has a five-year-old son, Raphael, from a previous relationship with comedian Gad Elmaleh.
Rassam, who has been married before, has a seven-year-old daughter.
