The Real Housewives of New York City is down four cast members, and now its Hudson River neighbor is having problems, too.

While Bravo fired Jill Zarin, Alex McCord, Cindy Barshop and Kelly Bensimon from New York, New Jersey cast members are jumping ship on their own.

Jacqueline Laurita (above, left) is Tweeting this week that she's done with the show.

After attending Jersey's annual fashion show for the boutique Posche, an event that brought drama in the past, Laurita Tweeted, "Someone (not me) got set up tonight. There are some sneaky people trying to make someone look bad & then play innocent on camera. Sad."

Cameras were rolling to film season four (season three is currently airing.)

Laurita also Tweeted that she does not plan to attend the season three reunion taping:

    "No reunion for me. ... I'm tired of the BS & ... low life people.I didn't know this was what I signed up 4. ... I can't be part of the Charade anymore. ... I'm a REAL housewife. ... There is no real love there. ... I'd like to only focus on positive things now please.I threw the trash out.I'm cleaning now and reorganizing.Starting fresh and new."

Teresa Giuidice also sent out some revealing Tweets on Thursday -- keep reading (she was supposedly slapped by Laurita) ...
