Vinny threatened to leave a few days ago, after he complained of "being homesick." We're told the cast was able to talk him into coming back, but that didn't last long.
Sources connected with the show say Vinny has been a pain in the ass and no one will be getting on their knees, begging him to come back.
TMZ spoke with executive producer Sally Ann Salsano, who tells us, "We do not comment on the production of the show."
