The founder of the fashion house Valentino also attended the ceremony.
A few months before marriage, 21st March, the couple had a son Alexander Andrea Stefano Casiraghi or simply Sasha.
Andrea spent his childhood between France, Italy and Monaco.
Secretive by nature, he made his first public appearance at the age of 19 during the 43rd Monte-Carlo Television Festival.
In 2004, his younger sister Charlotte introduced him to her friend and classmate, a member of the Colombian aristocracy Tatiana Santo Domingo, who happened to be a daughter of one of Colombia’s richest businessmen.On 31 March 2005, the Palace of Monaco announced that Hereditary Prince Albert would take over the duties of his father as regent since Rainier was no longer able to exercise his functions as sovereign.This decision was reached by the Crown Council of Monaco, a body made up of notable local figures with residual powers to make judgments about certain constitutional matters.He has also been a corporal in the Compagnie des Carabiniers du Prince since 20th January 2012.A contrast to her silk wedding gown with five-metre long train, which included 40,000 Swarovski crystals, 20,000 mother of pearl tear drops, the evening's dress was fortunately a more lightweight affair.
