7. Diane von Fürstenberg

Diane von Fürstenberg is another celebrity to own a luxurious boat, and at 305 feet long her EOS yacht is one of the largest in the world. Diane often takes advantage of the mammoth vessel, holding frequent parties, having guests over, and even loaning it out to her celebrity friends. But the one rule everyone aboard Diane’s yacht needs to follow is that they need to have their footwear off!
