'Real Housewives Of New Jersey' Reunion Part 2 Preview: Jacqueline Says Teresa Caught Joe Cheating

Season 4 of "The Real Housewives of New Jersey" was so jam-packed with drama that Andy Cohen needed to split the reunion into three separate episodes just to fit it all in. A preview of the "RHONJ" reunion Part 2 reveals that Jacqueline Laurita has had enough of Teresa Giudice and is ready to air all the dirty laundry.

Jacqueline reveals in Part 2 of the "RHONJ" reunion, which airs next weekend, that Teresa once caught her husband Joe cheating.

"You walked in on your husband when he had somebody on the desk in his office," Jacquline says to Teresa when Joe joins the girls on the reunion couch to discuss his questionable behavior this season.

In an episode that aired in August, Joe called Teresa some horrible names, including "bitch," while on a phone call in California.

Regardless of Joe's behavior, Teresa will supposedly never leave him.

"Teresa will never, ever leave Joe. She adores him and will always make excuses for his behavior," a friend of hers told HuffPost reporter Naughty But Nice Rob. "He was caught on tape talking with a mystery woman, calling his wife a 'bitch' and a 'c***' and she chose not to see the red flag. Even if she caught him naked with another woman, she would believe that the wind blew both of their clothes off!"

During Part 1 of the "RHONJ" reunion, tensions ran high between Jacqueline and Teresa, whose friendship crumbled in Season 4. Things got personal when Jacqueline attempted to talk about her son Nicholas' autism diagnosis, but Teresa wanted the attention back on her.

Teresa said that her daughter Audriana and Nicholas were once boyfriend and girlfriend, but they broke up, a comment that made Jacqueline's sister-in-law Caroline Manzo furious. She told the "Fabulicious!" author that the moment was not about “[you and] your fucking Christmas pageant dress, sit back and shut the fuck up."

After Part 1, Teresa reached out to her Twitter fans.

Part 2 of "The Real Housewives of New Jersey" reunion airs Oct. 7 on Bravo.
