Holding Out for
Sources close to the cast tell TMZ, the "Jersey" stars in question realize the joyride might be coming to an end -- and they want to milk MTV ... while they still can.
Another disputed point -- the number of personal appearances, which can pay up to $40,000 a pop. MTV is adamant about limiting that kind of exposure, but the guidos and/or guidettes in question wanna get that cheese.
So far, we're told only Ronnie has signed -- and while the rest plan to follow suit (duh) ... they better do it fast. Season 4 is scheduled to start shooting in Italy within the next few weeks.
Calls to MTV weren't returned.
