    Prince Pierre Casiraghi, Son of Princess Caroline of Monaco

    Prince Pierre Casiraghi, 25, is third in line to the throne of Monaco. But his royal responsibilities haven't stopped him from living extravagantly.
    In fact, he reportedly dropped out of school and is known as the "party prince," according to The Daily Mail.

    Prince Pierre supposedly regularly appears at nightclubs around Europe and the U.S., dropping cash on expensive bottles.

    Earlier this year, he wound up in the hospital after a brawl with a nightlife impresario at a Manhattan club, who later told The New York Post that the prince and his entourage “were being completely obnoxious,’’ insulting the models and swigging from a $500 bottle of vodka on his table.
    He's now suing the club, Double Seven.
