Teresa Giudice: I Was Naïve to Think That The Real Housewives of New Jersey Would Be Fun Again

"Just be careful," she warns her new co-stars during the reunion special

When Teresa Giudice joined the cast of The Real Housewives of New Jersey in 2009, she imagined it would be a good time. But as cameras captured her worst moments, from flipping tables to pleading guilty to fraud charges, the Bravo reality star said she's had a change of heart. During the second part reunion of the reunion special, host Andy Cohen asked how it felt to have Dina Manzo rejoin the fray.

"I was like, 'This is going to go back to season one. I came on the show for fun and it went a totally different way,'" Teresa, 42, said of the show's drama. "I mean, look at where I'm at now. I was so naïve."

"There were people that came on the show that tried to hurt Joe and I. Some of them were housewives and some of them were strangers. Like, even people that just came to parties started a lot of trouble."

"Just be careful," she told her co-stars. "There are people that come on the show that try to hurt you."

Still, Teresa said she has "changed for the better" since the show started. "I don't let the petty things bother me anymore," the mother of four explained. "I just worry about the important things in life."

Regarding their jail sentences, Joe added, "I gotta blame myself. Who else am I gonna blame?"

The reunion also showed Amber Marchese accusing Bobby Ciasulli of staying with Nicole Napolitano just for TV. "I had a lot of conversations with Bobby," she said. "And they weren't good about Nicole."

"He didn't seem like he loved her and he would have done anything to be on that show," the cast's obvious outsider continued. "If his contract hadn't come through, he was hightailing it out of there."

"He wanted to be on the show," Jim Marchese said. "He would have done anything to be on the show."

To prove his point, Jim showed several photos of Bobby throughout the years, where he posed with Teresa, Melissa Gorga and Jacqueline Laurita. "Fame whore!" Jim shouted. Bobby, meanwhile, maintained the meetings happened by chance, saying, "I did not go seeking anybody out like a moron."

"This show," Dina Manzo said, "is so f--ked up."

Part three of The Real Housewives of New Jersey reunion will air Tuesday at 8 p.m. ET on Bravo.
