Diane Von Furstenberg's elaborate name comes from the fact that she used to be a princess. She married Prince Egon of Furstenberg decades ago. They split in 1972, but she liked the name so much that she kept it, and used it during her fashion career.
Years later, she met and married businessman Barry Diller, who's made billions of dollars trying to save the rest of us money on our travel plans through his website, Expedia. They've been together since 2001.
