The grandson of Grace Kelly is taking the royal plunge.
Andrea Casiraghi and longtime love Tatiana Santo Domingo will wed Aug. 31 at a private ceremony held in his homeland of Monaco, according to People.
The couple met seven years ago and became engaged in July 2012, four months after welcoming a son, Sacha.
Casiraghi was introduced to his 29-year-old bride-to-be by his sister, Charlotte. He is the oldest son of Kelly’s daughter, Princess Caroline.
Casiraghi, 29, is currently second in line to succeed his uncle, Prince Albert II, as ruler of the city-state on the Riviera.
Santo Domingo is a fashion designer and Colombian heiress. The two both attended school at the Lycee Fontainebleau in Paris.
