The Year's Most Lavish Royal Wedding is Happening This Weekend

It's been a big Summer for the British royals and we got to see the Swedish royals get married in a lavish ceremony, but now the Monaco royals are grabbing the spotlight! Pierre Casirahgi and his girlfriend of six years, Beatrice Borromeo, made it official with a wedding last Saturday. The civil ceremony at Monaco's Pink Palace was followed by a garden party and a reception at Monaco's Hotel de Paris. But the "low-key" celebrations weren't the only plans for the couple's nuptials, since they'll have a more extravagant religious ceremony on Beatrice's family's private islands in Italy this weekend.

Twenty-seven-year-old Pierre, who is the son of Princess Caroline of Monaco and the grandson of Grace Kelly, met Beatrice in 2008 when they were both studying at University Luigi Bocconi in Milan. They became engaged in 2014 after Pierre proposed with a pear-shaped pink diamond. While he's seventh in line for the throne of Monaco, 29-year-old Beatrice, who is a journalist and TV host, has her own impressive family history. She is the daughter of two counts and has seven cardinals of the Roman Catholic Church, including an archbishop of Milan, who was also a saint, in her aristocratic lineage. The Borromeo family still owns the majority of the Borromean Islands on Lake Maggiore in Italy, which they have owned since the 17th century.
