Will Jersey Shore Season 4 include new cast members

When MTV takes the Jersey Shore cast to Italy next month to film Jersey Shore Season 4, they won't be adding any new cast members, the show's co-creator confirmed today (Thursday).  We're happy with our cast," Sally Ann Salsano told Entertainment Weekly in an exclusive new interview.
Unlike the original MTV reality show - Real World - Jersey Shore producers have kept the entire original cast on for what's going on four seasons. The only change has been when original cast member Angelina Pivarnick walked off the reality show for good during the filming of Jersey Shore 2 in Miami. That left seven housemates and opened the door for producers to bring Snooki's longtime friend, Deena, on as a surprise roommate at the start of Jersey Shore Season 3.  After a somewhat shaky start, Deena bonded with the rest of the housemates and has been welcome by the millions of Jersey Shore fans.
