The 29-year-old crown prince of the Grand Duchy of Luxembourg is the next in line to throne and is a graduate in political science from the Institut Albert-le-Grand in Angers.
Quite publicity shy, he has had one serious relationship in the past (with Pia Haraldsen from the Norwegian royal family). His low profile has always irked the paparazzi and not surprisingly earned him the sobriquet 'The Private Prince'.
