Brooklyn Nets owner Mikhail Prokhorov wanted to buy a house. Not just any house: Lily Safra’s Villa Leopolda, in Villefranche-sur-mer, France. And then, according to Forbes, Prokhorov backed out at the last second, losing his deposit.

The estate is reportedly one of several waterside homes that King Leopold II of Belgium built for his many mistresses.
