Forget the bad blood between the "Jersey Shore" crew and the locals in Italy — now it appears that the cast members are turning on each other.

TMZ reports that "Shore" castmates Mike "The Situation" Sorrentino and Ronnie Ortiz-Magro got into a physical altercation Monday night.

While Sorrentino reportedly got the worst part of the deal, both of them sustained injuries, with Ortiz-Magro's knuckles scraped up from pummeling Sorrentino's face, which now bears red marks from the thrashing.

The dust-up reportedly occurred after an argument between Ortiz-Magro and Sammi "Sweetheart" Giancola.

The pair, along with Nicole "Snooki" Polizzi and the rest of the "Shore"-heads, are currently filming season four of MTV's hit reality series in Italy.

MTV and Sorrentino's representative did not immediately return TheWrap's request for comment.
