MTV is laying the law down on their 7 guidos and guidettes! After both The Situation and Vinny had “quitting the show” moments and each left for a brief hiatus…the big wigs up at 1515 want to make sure there will be NO more scares. Hit the jump for details.

Sources connected with production tell TMZ, the network is serious this time: if another cast member tries to walk off the show … that person will be fired, and the remainder of his or her contract will be terminated. No exceptions.

We’re told it’s all a power play. With two cast members nearly jumping ship in the same week, MTV wants to reassert some authority … and show the cast who’s boss once and for all.
