In true late-season “Real Housewives” fashion, the gloves have come off.

As the third season of the “Real Housewives of New Jersey” winds down – amid word that Jacqueline Laurita quit the show and did not attend the finale taping – two previously friendly cast mates are now coming to blows.

Verbal blows, that is. When rumors surfaced that Melissa Gorga once worked as a stripper, Jacqueline began implying on her Twitter that Melissa’s sister-in-law, Teresa Giudice, was behind the buzz.

“Teresa told me that ‘rumor’ about Melissa when she first started the show,” Laurita Tweeted Saturday. “She wanted her out then. She knew. She plotted it. She played dumb on camera and even defended Melissa.”

And in a separate Tweet: “Teresa is scum!”

No response yet from Giudice, but as for the alleged stripper in the mix, she took to her website to refute the rumor.

“We are filming season 4 so there is not too much I can confirm, but there is one thing that I would like to clarify …the accusation that I was once a dancer at a strip club,” Gorga writes. “This is 100% NOT TRUE. I did bartend fro a few weeks at a bikini bar while I was in college. My outfit was a tank top, shorts and sneakers. SORRY, no bubbies there.”

“The reason I am so adamant about clearing this up is because people are making false accusations solely to hurt me and my family,” she continues. “Someone desperately wants to knock me down and prove that I have something to hide, but then tries to cover it up by putting the blame on production.”

Laurita, meanwhile, claims to be stepping back from the drama.

“OK, so I’m losing it,” she Tweeted Saturday. “This is what all this negativity I’m surrounded w/does 2me. I’m taking deepbreaths&gettingcontrolofmyself.”
