Prince Lorenzo Borghese
In addition to his reality TV appearances (he was also on Celebrity Big Brother UK in 2012), Lorenzo is known for his high-end line of organic pet products called, wouldn't you know it, "Royal Treatment," and his involvement in a private-label Italian cosmetics company. Like another on this list, he too followed in his grandmother's footsteps - Princess Marcella Borghese founded the "Borghese" cosmetics line in 1958. These days you can find him back in Florida where he runs his South Beach Brewing Company and animal rescue charity along with his pet care brand.
