Simon Cowell, Net worth: $570 Million – Slipstream, Estimated $350K Per Week

Simon Cowell works really hard, and this is why he has an enormous fortune in the bank. Judging talent competitions on TV can get quite tiring, but Cowell definitely knows how to relax and unwind when his schedule allows it. He was already once seen enjoying a fun vacation on a gorgeous superyacht called the Slipstream. The superyacht comes with a VIP lounge, seven cabins, and a number of jet skis. Cowell is currently worth around $570 million, so renting a yacht for $350K a week is a piece of cake for him.
