Andrea Casiraghi (right) appears at a balcony in the royal palace for The National Day of Monaco (in French, La Fête du Prince) on November 19, 2006. Is he grimacing? It looks like he's grimacing. Andrea is joined by his sister Charlotte Casiraghi (center front) and his brother Pierre. Their mother, Princess Caroline, is in shadow at left. Andrea Casiraghi was born in 1984, so he turned 22 the year this photo was taken.
