Teresa Giudice and Joe Gorga's family feud leads to a massive brawl on The Real Housewives of New Jersey , with Joe Giudice wrestling his brother-in-law to the ground.

The upcoming episode (airing July 21) continues where the drama left off, with the two men literally on top of one another. In the preview clip, Joe's wife Melissa Gorga and others desperately trying to pull them apart. Melissa screams "Help your brother!" at Teresa as she runs out of the room in search of the cops.

But there are plenty of more surprises in store.

An insider tells EnStars that after the dust settles, L.A. Shrinks's Dr. Venus Nicolino (known as Dr. V on the show) arrives just in time to help the siblings.

Teresa is seen crying in the preview clip, but it is unknown if the psychologist's breakthrough helped she and Joe Gorga work through their issues. Melissa seemed to shed a little light on the current status of the family fued.

"Welcome to rock bottom. We hit it hard in this episode, and it was NOT a soft landing, believe me," Melissa revealed Monday in her Bravo blog. “I’m not proud of some of the things I said. I certainly don’t enjoy watching us at our worst. We do eventually figure out a way to climb up from rock bottom.”

The Real Housewives of New Jersey airs Sunday at 8p.m. on Bravo.
