Nice girls finish last! Lisa Hochstein just wants everyone to get along with Adriana De Moura on The Real Housewives of Miami, but apparently that's asking a bit too much. 

In this new sneak peek clip of the Monday, Oct. 28 episode, some of the ladies attack Hochstein's "peacemaker" attitude, charging that De Moura's done too much damage to forgive. The most offended is Joanna Krupa -- the victim of De Moura's literal slap in the face.

Krupa goes off, and says she refuses to forgive the dark-haired villain after she called her a "hooker" and slapped her in the face. 

And when Hochstein calls her "delusional," it's the last straw. 

"You know what f*** you," Krupa screams at Hochstein. "You call me delusional, you're not in my wedding party, get the f*** out of here!"

Those who have seen Krupa's wedding photos know Hochstein is eventually welcomed back into the bridesmaids fold, and the two friends even share an adorable dance, but things are beyond tense in this pre-wedding clip.  

The Real Housewives of Miami airs Monday nights at 10 p.m. on Bravo.
