'Jersey Shore' Sneak Peek: Snooki and Jwoww Fight (VIDEO)

Already on this season of "Jersey Shore," we've seen Ronnie and The Situation have a brawl, Snooki and Deena start fighting (and then, later, make out), and Ronnie and Sammi go at it again. Who's next to start fighting on the show? Looks like Snooki and Jwoww, if this preview clip is any indication.

The preview of tonight's episode features Snooki and Jwoww getting into a screaming argument after a night of partying, in which Snooki has done something to seriously upset her boyfriend, Jionni. The poor shmuck has been playing a role in this season of "Snooki's embarassed boyfriend," who consistently gets upset with her over trying to dirty talk with him over the phone in front of a national TV audience.

From the sound of things, Snooki took things too far and Jwoww is on Jionni's side. She yells that she's here to give Snooki a "reality check," and says that she's acting like a "f***ing a**hole." Is she really? We'll have to see tonight.
