Fashion designer Diane von Fürstenberg was already successful on her own, but getting married to wealthy businessman Barry Diller just made her life fill up with even more luxury. Diane and Barry reportedly own a very nice yacht called the Eos, for which they spent a whopping $100 million. Bill Langan and Francois Catroux are the guys responsible for how the yacht looks like. The couple apparently loves throwing parties on their yacht. As of today, Diane and her husband Barry have a joint fortune which is estimated to be around $3.5 billion.
