It must be nice to receive an inheritance of $800 million on your eighteenth birthday, and lucky for her, that’s the life that Athina Onassis lives. Athina is the last descendant of the Greek billionaire Aristotle Onassis, who was once married to the great Jacqueline Bouvier Kennedy. At one point in time, Athina was estimated to have a net worth of more than $5 billion.
