NEW YORK CITY, NEW YORK: Teresa Giudice, Joe Gorga, and Melissa Gorga's conflict is far from over, as it's about to hit new heights. Teresa labels her brother and his wife Melissa "disgraceful" in a preview of the third installment of 'The Real Housewives of New Jersey' Season 13 reunion for allegedly cooking up the story about how her daughter, Gia Giudice, said Joe could "do better" than Melissa.

The 'RHONJ' Season 13 reunion has been intense thus far, and the teaser for the third installment is no exception, as it contains glimpses of Teresa storming off the set. Teresa and Melissa have been feuding since the latter joined the show in Season 2. She is seen bursting on Melissa and her brother Joe in a new peak for the third part of the reunion before calling Gia, who denies the claims of her uncle.

Gia is sad as Zio Joe calls her a 'liar'

Teresa's daughter confronted her uncle Joe in a sneak peek for the highly anticipated 'RHONJ' Season 13 reunion episode, which premieres on June 13. During the episode, Teresa called Gia to discuss her uncle Joe's recent accusation that she advised him he "could do better" than his wife Melissa amid the family quarrel. Joe claimed that Gia called him after his sister Teresa and her husband, Louie Ruelas, asked him to their home to reveal that Melissa had cheated on him. Joe is heard saying, "So she can lie for you? Of course, she is. What, am I gonna make this up?" Melissa added to the drama by asking, "Why would he ever make something like that up?"

After the accusation, Teresa quickly grabbed her phone and stated, "I’m gonna call my daughter right now." Andy Cohen was then seen grabbing Teresa's phone and asking Gia to explain what she said to Joe. "I called him regarding the wedding saying that he should do the right thing," she stated over the phone. "[And] that Nonna and Nonno are looking down on them, and my mom wanted him to walk her down the aisle." She said, "I never told him that he could do better than my aunt Melissa. And it’s sad, Zio Joe, that you’re trying to call me a liar."

Teresa storms off the set

After the call with Gia, Teresa addressed her younger brother with tears in her eyes, saying, "I just don’t understand this, I was always good to you. I always put you first. We were best friends. This is absolutely disgraceful. I really can’t." Ultimately, she stood up and marched out of the set yelling. "You’re f**king disgusting. Disgusting! This is not how I would raise my children, ever! Mommy and Daddy, you should be ashamed of yourself." Teresa yelled, "And, don't come following me," before leaving, and then Melissa is seen snarkily commenting, "She's embarrassed."

Part three of 'The Real Housewives of New Jersey' Season 13 reunion premiers Tuesday at 8 pm ET/PT on Bravo. Head to Peacock the next day to catch an unedited and extended version of the episode.
