MTV is planning something of a twist for the upcoming second season of Jersey Shore, which will premiere July 29. While the original cast is currently filming in Miami, the second part of the season will see the cast return to Seaside Heights, New Jersey, where they will be joined by… several new cast members! It’s not clear how many people will be added and whether or not any of the original cast members will be replaced. What is clear: there will be a plethora of sloppy and inebriated Old Blood/New Blood dance battles at Karma. [EW]
