We knew things between Teresa Giudice and Jacqueline Laurita were really bad, especially after the Season 4 Reunion was filmed earlier this month, but now their relationship has become truly toxic.

In a Twitter rant on Sept. 26, Jacqueline threatened to sue her RHoNJ co-star, tweeting, “Teresa shouldn't go on TV to say I'm threatening her unless she wants a defamation suit against her. I've tried 2get her to stop & she doesn't.”

Jacqueline is referring to Teresa's appearance on Anderson Live, in which Tre said that if she keeps getting texts from Jacqueline she will "go to the cops."

However, Jac later backed down and tweeted, “Sorry, lol, I was having a moment. It's all good now. I get frustrated sometimes.”

“Let's make a deal @teresa_giudice I won't interfere in ur life if ull stop interfering in mine. Lets keep each others name out of our mouths,” she concluded.

Teresa has yet to respond, but we bet she’ll have something to say sooner or later.
