Kylie Jenner is plunking down $1.2 million a week to charter Tranquility, a 300-foot megayacht. Insane on so many levels, but there are other yachts that give hers a run for her money. Also Mystikal took a terrible fall during a concert Thursday night in Tampa ... it was so bad his concert got cut short by more than half and he couldn't walk off the stage without a major assist.
