Call it a really bad case of sibling rivalry.

In a sneak peek at Sunday’s The Real Housewives of New Jersey, Teresa Giudice and her brother Joe Gorga (whose wife Melissa is also a Housewife) are at odds once again. This time, they’re fighting over Teresa’s husband, Joe Giudice, and how he treats her.

“How does your husband treat your kids?” Gorga asks during a workout. “How does your husband treat you? I go home and I treat my wife like a queen so my sons can see that.”

“You should ask my daughters how my husband treats me at home,” Teresa responds.

“I don’t like 90 percent of the things that it does – I can’t even call him a man,” Joe continues.

Then, Teresa tosses water all over Joe. “I’m done with you,” she says as she storms out.

The shouting continues as Teresa leaves the gym.

“For my brother to bring that up is so f––ing low, insinuating that my husband is not a good father to my children or not a good husband to me,” she says later. “Keep your f––ing mouth shut.”

Joe then calls Teresa’s husband a “bankruptcy guy” and a “cheater.”

The Real Housewives of New Jersey airs Sundays 8 p.m. ET on Bravo.
