Mike SorrentinoIt looks like things are falling apart at the Jersey Shore.

The resident nice guy, Vinny Guadagnino abruptly left the 'Jersey Shore' house on July 1 in the middle of filming, and now it seems that Mike 'The Situation' Sorrentino has done the same.

Us Weekly is reporting that Sorrentino has abandoned his costars and decided to head home early. An insider dished, "Mike walked off the show. He's so over the whole thing, I don't think he's coming back. Everyone in the house is so unhappy."

The cast returned from their trip to Italy and began filming their fifth season back where it all began, Seaside Heights, NJ. Something mustn't be clicking for the crew of outrageous characters, Guadagnino apparently left the show after an argument with an unnamed castmate and although it's unknown why The Situation vacated the premises, it looks like the wheels are falling off of this money making machine.

What is the 'Jersey Shore' without The Situation?
