Andrea Casiraghi, eldest son of Princess Caroline of Monaco and her late husband Stefano Casiraghi, will tie the knot with his Columbian fiancee Tatiana Santo Domingo on August 31. The New York-born bride-to-be -- later raised in Switzerland and France -- is the daughter of Julio Santo Domingo, Jr. and former Brazilian socialite, Vera Rechulski. She's the granddaughter of Columbian tycoon Julio Mario Santo Domingo, who died in 2011.
Casiraghi and Domingo, both 29, met as teenagers and have been together for eight years. The Monaco palace first announced their engagement in July 2012.
In addition, the couple already has a child together. The heiress gave birth to their son, Sacha, at London's Portland Hospital in March.
