Sorrentino reportedly returned to the Jersey Shore cast's apartment with red marks covering half his face near his left eye, while Ortiz arrived at a separate time with just his knuckles cut and bleeding.

Although they split during Jersey Shore's third season, Ortiz and Giancola were photographed walking through the streets holding hands and enjoying a romantic private dinner date at a restaurant earlier on Monday, the U.K.'s Daily Mail newspaper reported.
