He is 3rd in line to the throne of Monaco after his mother Princess Caroline and brother Andrea Casiraghi. He isn't technically a prince because his mother had him take his late father's last name, but he is still royal. Contrary to popular belief he is much hotter than his older brother Andrea, but it is alright since his brother gets to be the sovereign leader and all. A bit of a man-whore but recently is tied down to Beatrice Borromeo. He is the hottest royal alive (unless you like the dark haired boys and then the title goes to Prince Carl Philip of Sweden).
Person 1- Who is the hottest royal?
Person 2-Prince William?
Person 1-Are you retarded? Prince William is totally bald! Pierre Casiraghi is the only answer.
