Andrea Casiraghi looks regal in church

His tie is just a hair off, but Andrea Casiraghi otherwise looks every inch the young royal as he attends the annual Thanksgiving Mass as part of Monaco's National Day celebrations. This was at the Cathedral Notre Dame in Monaco on November 19, 2009. Andrea Casiraghi was born in 1984, so he turned 25 the year this photo was taken. Regal he may be, but Andrea Casiraghi is not very likely to ascend to the throne of Monaco; the twin children of Prince Albert and Princess Charlene of Monaco come first.
