The "Real Housewives of New Jersey" cast are not too pleased with Teresa Giudice.

During the Sept. 7 taping of the reunion special, tempers flaired and it was the whole cast vs. Teresa. Apparently none of the cast members have spoken to her since last season's reunion, which took place a day after the big fight (its set to debut on Sept. 23) for the show's season finale, including her brother Joe Gorga.

The episode dubbed, "Strippergate," took place more than a year ago.

"The reason Joe hasn't spoken to Teresa is because of the stripper drama. Joe revealed at the reunion that Teresa told their father that Melissa was a stripper and that their father went back to Joe Gorga and told him Teresa said that," a show insider told AllAboutTRH.

The source claims that Teresa denied telling her father that and said she just heard it was a rumor, but Joe's mind was already set -- he didn't believe his sister.

"Things got real ugly between them but Teresa got extremely emotional talking to her brother who she had not seen in a year."

On 'Watch What Happens Live!' Teresa shared Joe's "lies" with host Andy Cohen. Teresa said she called her father and he denied ever telling her brother Joe that. However, Cohen stopped her from revealing anymore about the reunion.

Things also got nasty between Teresa and the other cast mates. Her cousin, Kathy Wakile, even targeted Teresa's mother.

"Kathy calls Teresa's mother a liar which makes Teresa freak out. I think that got Teresa upset the most and Caroline is seen even comforting her," the source claimed.
