Pauly D, Snooki and the gang are heading back from Italy in less than a week….and were scheduled to get right back to work on the 26th filming down at the Jersey Shore for season number 5 of the cash cow show. But the guidos and guidettes know an opportunity when they see one…and have decided to hold out for even MORE money for the season. Get those MTV dollars!! Details after the jump.

Plans are already in motion for a fifth season back in Seaside Heights — but sources connected with the “Jersey” cast tell TMZ, Pauly D and the gang refused to take part without signing new contracts first.

We’re told MTV originally planned to shoot the new season under the terms of the Season 4 contracts — but lawyers for the cast refused … so MTV drew up new papers.

We’re told the majority of the cast has already re-signed for a bump in salary — not a HUGE raise, but still significant — and the rest will sign this week.

The cast is scheduled to fly back from Italy on the 23rd — and start shooting the new season in Jersey on the 26th. 495 Productions has not returned calls, and MTV had no comment.
