While partying at the annual desert bacchanalia called Burning Man in Nevada, 19-year-old Olivia met Tao Ruspoli, who is a photographer, documentary filmmaker, and a bona fide Italian prince. They married a couple of weeks later in an old-school bus in Virginia. "I didn't know he was a prince when I fell in love with him...and the bus," she told David Letterman in 2009. Even though, she was technically a princess, she and Ruspoli ended up living together on said bus for a spell in Venice, CA. "It's a cool bus," she told "It's not your average school bus." They file for divorce earlier this year.
