Grace Kelly's Grandchildren Live Extremely Lavish Lives

Grace Kelly's eldest grandchild Andrea Casiraghi was born in Monte Carlo on June 8, 1984, and is the son of Princess Caroline and Italian businessman Stefano Casiraghi, who was killed in a boating accident (per Hello!). Although he does not have the title of a royal, Casiraghi is fourth in line to the Monégasque throne (per Town & Country) and has the charm and classic good looks of a Disney prince. He grew up on a picturesque French country estate and went to school in Paris. Like his father, who was a lover of outdoor sports, Casiraghi is an avid skier, horserider, footballer, and long-distance runner — and if that's not impressive enough, he's also multilingual, speaking French, English, German, and Italian (via Hello!).

In 2013, Casiraghi wed New York-born Columbian billionaire heiress Tatiana Santo Domingo, the owner of an ethical fashion brand and the granddaughter of a beer brewing mogul (via Insider). Santo Domingo, a regular guest at Fashion Week, is listed as the wealthiest citizen of Monaco and is estimated to be worth $1.7 billion (via Forbes). Casiraghi and his wife currently live in London with their children (via Insider). 

Like his grandmother Grace Kelly who was committed to charity work, per the Monaco Tribune, Casiraghi is the patron of the Motrice Foundation, which funds research into cerebral palsy (per Vogue).
