Turns out Hef's 19-year-old handpicked twin successors to the throne of Holly, Bridget and Kendra come with a checkered past. Karissa (left) and Kristina Shannon (right) -- who have recently moved into the Playboy Mansion -- were both busted by St. Petersburg, Fla. police for felony aggravated battery back in January. They both received probation and were ordered to pay restitution to the two victims.
