Heather Thomson and Ramona Singer have not gotten along since they first met on The Real Housewives of New York Season 5. The feud first started when Heather refused to invite Ramona on a girls trip to London. Then, Ramona called Heather a liar and accused of her hiding behind her smile. It seems like these two have been fighting for months on end.

This week’s episode of RHONY was no different with the two ladies getting into a very un-ladylike screaming match at a socialite’s party. Heather was upset because she overheard Aviva Drescher and Ramona talking behind Jacques back after he had left the party. Heather approached Aviva to tell her that was upset with her behavior and Ramona overheard the conversation, taking it to mean that Heather was talking behind her back.

Ramona flew into a rage, screaming at Heather for allegedly being sneaky. “You talk behind my f***ing back, I'm sick of it, stop it,” Ramona yelled at Heather. The newbie Housewife, who was clearly in an emotional state, accused Ramona of not having any “balls” and telling her that she shouts and runs aways from arguments.

We’ve seen these two argue before but this has to be the most vicious argument we’ve ever seen them have on the show. And -- guess what! -- the argument won’t even be over until next week’s episode. That right, this is a two-part argument.

The Real Housewives of New York airs Mondays at 9 p.m. ET/PT on Bravo.
