The Daily Grind Video

Season 6 of Jersey Shore has just started filming, and already it sounds like there’s some serious drama!

The cast of the hit MTV show recently was involved in a “massive” bar brawl, and things got pretty ugly.

A source told Us Weekly:

It started as a small fight, then turned into a massive brawl. Jenni’s boyfriend beat up a few guys, Pauly knocked some guy out, [and] Ronnie [and] Sitch were all there as well, fighting off guys. Jenni sprained her ankle. It was rough.
These drunk guys saw the cameras and started taunting the girls. Then, they started bothering Ronnie, Vinny, The Sitch, and Pauly.

Apparently it was more of the cast’s friends that got more involved:

They came back and got in their faces. Rodger and Ryan [Labbe, from MTV’s The Pauly D Project] stepped up and all hell broke loose.
It became a club-wide brawl . . . Ronnie, Sitch, Ryan, Rodger and Pauly were fighting five guys, and bouncers too . . . Jenni was fighting with the guys.

The source also said that Vinny was off with girls at the time, and Snooki wasn’t even there!

We just have to wait to see the footage of what exactly went down!
