Andrea Casiraghi and Tatiana Santo Domingo are to wed on 31 August, according to French publication Paris Match.
It has been reported that the couple, who have been engaged for a year and together for eight, have set the date for a Monaco wedding, and that the invitations have already been sent – although the Palace has not yet confirmed that the nuptials will take place.
The Monegasque royal and his fiancée met through Andrea’s sister Charlotte, who turned 27 on Saturday, as the two young women attended the same school in Fontainebleau.
Good news keeps coming in the Grimaldi family. The couple welcomed a baby boy on 31 March at London’s Portland Hospital, who they have named Sacha, and Charlotte is thought to be expecting a child of her own.
It is thought that Charlotte is in her second trimester of pregnancy, although the Palace has yet to confirm the news.
Much like Kate Middleton, Tatiana exudes humility and has perfected the art of being a discreet yet supportive consort. Her low-key approach is something the Monegasque royals – Caroline in particular – appreciate. Since establishing their relationship, the couple have stayed away from the media spotlight.
Tatiana is the granddaughter of the late Colombian mega-mogul Julio Santo Domingo, and is set to inherit an estimated $6bn fortune which she will share with her younger brother Julio Mario Santo Domingo III.
Despite her vast wealth she has worked hard to establish ethical fashion brand Muzungu Sisters, which she co-founded with business partner Dana Alikhani, daughter of the late Iranian businessman Hossein Alikhani.
Andrea and Tatiana’s first child is not a potential successor to the Monegasque throne given that they were not married when he was born.
Prince Caroline of Monaco’s eldest son Andrea is second in line of succession to the throne of Monaco, following herself.
