"The Real Housewives of New Jersey" Napa Valley trip was emotionally draining for Teresa Giudice. First, her husband, Joe, called her a b*tch and a c**t, and then she found herself dueling with fellow cast mate Caroline Manzo.

In the episode that aired Aug. 26, Manzo, 51, continued to hold a grudge against Giudice's "Fabulicious" cookbook, where Giudice, 40, called her "as Italian as the Olive Garden." Additionally, the TV cast as a whole believe Giudice has been selling false stories to the tabloids.

"This is why I want nothing to do with you -- you are a disgrace! I'd like to admit what you've done to me. Tell me the truth: That you meant to do that to me in the cookbook. Tell me you hate me!" Manzo said to Giudice in a rage.

Giudice defending her statement by maintaining it was a "joke" went on to say, "I have more class than you. I can definitely prove it to you on my kids. I'm telling the truth. I don't know how to lie. I never ever, ever, ever wrote one bad thing about you."

Giudice's cousin, Kathy Wakile, tried to mediate the situation, telling Giudice that Manzo "never did anything to hurt you," though Giudice insisted she had done enough apologizing for the comment.

When Giudice repeatedly denied accusations she made a seven-cover deal with a tabloid magazine, Caroline called her a liar, fraud and disgrace.

"I don't know how to lie," Giudice said, after which a angry Manzo responded, "I'm arguing with a sociopath ... she doesn't give two sh*ts about anybody."

Joe pulled his wife away from the situation and said they need to go to the airport to catch an earlier flight. But even as she walked out the door, Giudice put up a fight against the woman who called her an "ugly human being."

"She's a f**king c**t and can go f**k herself," Giudice said as she left.

One year later, WakiIe took a look back at the Napa Valley incident and analyzed her involvement in her Bravo blog.

"In retrospect, I do regret trying to reason with Teresa. It was an exercise in futility," she said. "I wanted to see a resolution between everyone in the hopes of leaving all the ill feelings behind in California and going back to New Jersey with a clean slate. Sadly I was mistaken."

Later in the blog, she wrote the following: "I tried to calm the situation. I went and sat next to her so she would not view it as an attack. I didn't want her to feel that there were sides and my intention was for unity not division. But herein lies the real truth. Nothing I said or did was working and nothing was going to. She would not consider anything I was trying to tell her. Teresa would have nothing of anyone's attempt to mediate."

Manzo does not regret what she said to Teresa Giudice, but does wish she had controlled her temper better.

Manzo reflected on the argument in her Bravo blog as well.

"I often wonder if I should have just got up and left the room, but the reality is that would have accomplished nothing," she said. "Bottom line is that this confrontation needed to happen. I said what I said, and I meant it, but I'm disappointed that I allowed myself to be brought to such a negative level."

She later wrote, "It's been a year since we were in Napa, and I've managed to put the season behind me. Life has been drama and nonsense free, and I like it this way. Lesson learned..."

After the episode aired on Aug. 26, Manzo and Giudice appeared on "Watch What Happens Live" and Manzo told host Andy Cohen the former friends still don't get along. According to RadarOnline, Manzo said she was angry in the episode because she felt Giudice only apologized for the cameras.

Giudice admitted she was paid for one magazine cover and told Cohen that "there are a lot of skeletons" in Manzo's closet.
