Teresa Giudice admits her expectations for initially starring on The Real Housewives of New Jersey turned out to be way off base.

"Going... back to Season One, I came on the show for fun and it went a totally different way," Teresa told Andy Cohen during the second part of The Real Housewives of New Jersey's sixth-season reunion Thursday, according to People.

"I mean, look at where I'm at now. I was so naive."

Teresa, a 42-year-old mother of four young girls, was sentenced to 15 months in prison after reaching a plea deal to resolve the 41-count federal fraud indictment she was facing with her husband Joe Giudice. She'll begin her jail time on January 5, after which Joe will start his 41-month sentence.

"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," Teresa reportedly recalled of her experience on the reality series.

Although Teresa recently hit an all-time low, she insisted she's "changed for the better" since first appearing on The Real Housewives of New Jersey in 2008.

"I don't let the petty things bother me anymore," Teresa explained. "I just worry about the important things in life."

Joe also reportedly admitted during the interview he blames himself for the events that have transpired, saying, "Who else am I gonna blame?"

The third part of the show's reunion will air on Tuesday at 8PM ET/PT on Bravo.
