Members of the 'Jersey Shore' cast are refusing to sign their new contracts, opting instead to hold out for more money.

LOS ANGELES, CALIFORNIA, UNITED STATES HOLLYWOODTV - Ronnie Ortiz-Magro may be MTV's new favorite 'Jersey boy'. That's because so far, only Ronnie has signed his contract for season 4 of 'Jersey Shore', which is scheduled to begin filming in Italy in the next few weeks. The rest of the cast has reportedly opted to hold out, refusing to sign their contracts until they get a better offer from MTV. Reports say that many of the castmembers realize that this may be the final season of 'Jersey Shore', so they're trying to cash in while the iron is hot. Supposedly, not only are the cast unhappy with what MTV is paying them, but they are also upset that MTV wants to limit their exposure, limiting public appearances for the cast. This is a point of contention, because castmembers can fetch up to $40,000 per appearance, and they want that cash too!
