Per ABC:
Prince Lorenzo Borghese, a handsome 34-year-old cosmetics entrepreneur, is an American citizen who has resided in Manhattan since 1997. He was born in Milan,
lived in Rome and outside Paris, and moved to Connecticut when he was five years old. Proud of his genealogy, his storied paternal ancestors include Pope Paul V (Camillo Borghese) and Cardinal Scipione Borghese, both of whom had an enormous influence on Italian art and beautifying Rome in the 1600s, and who helped finish St. Peter's Basilica.
Per Radar:
Then there's the question of where the 34-year-old Borghese is really from. Though ABC's website claims he was born in Milan and raised in Connecticut, his parents, Princess Amanda Borghese and Prince Francesco Borghese, have lived in the tony New Jersey suburb of Short Hills since 1979, and his permanent addresses from before 2001 all list him as a resident of the Garden State. You can take the Prince out of Jersey, but you can't take the Jersey out of the prince.
The title, at least, is legit—though it doesn't translate into a castle and throne (Throw a cannolli in the Piazza San Marco and you'll hit someone with a "royal" bloodline.) Although titles haven't even been recognized in Italy since 1947, Lorenzo is certainly milking his for all it's worth. When he decided to get into the family business of cosmetics, it was with a line of doggie grooming products, including the Stinky-B-Gone odor fighting kit, the Pumpkin Patch spritz, and the After Bath Pet Robe. Its name: Royal Treatment Pet Care.
