Prince Lorenzo??

Moving on to another matter that concerns those of us with spare time and on the subject of celebrity big brother there is another guy in there who calls himself Prince Lorenzo. Now he is meant to be a Prince from Italy which is strange as Itaky is a proud Republic with no Princes or Queens. So God knows why the hel someone is allowed to call himself a Prince? I though they needed a kingdom to induldge their out of date fantacies??
