Last night on The Real Housewives of New York (Season 5, Episode 4: “Diss-Invite”) Ramona Singer and Sonja Morgan got into a big fight over Sonja attending Heather’s London “girls’ trip” even though Ramona had been purposefully not invited.

The tension bubbled up at Sonja’s Social Life magazine party, where Ramona became so enraged that she told Sonja that she didn’t know what she was talking about, and then called her BFF an “airhead” and said she has “diarrhea of the mouth.” Yikes!

Being a friend of Ramona’s means that you are no stranger to a little argument here and there, but this fight seemed particularly vicious. Do you think Ramona and Sonja can get past this issue and remain friends? Vote below

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