These ladies are having trouble flying above! The third and final part of The Real Housewives of Atlanta's season six reunion, arguably the most dramatic, epic Housewives reunion ever, airs 8 p.m. Sunday, May 4 on Bravo—and Us Weekly has a first look at a yet another emotional, angry battle between the women.

This time, it's Kandi Burruss who raises her voice and points her finger to accuse Nene Leakes of wrongdoing.

"I try not to address anything that hasn't been talked about on the show," the Grammy winner says, turning to Leakes, who sits beside her on the couch. "But you do it all the time." Burruss' particular complaint has to do with a comment Leakes had made about her mother, Momma Joyce, suggesting she was "low in the gutter." Charges Leakes in the tense exchange: "That s--t pissed me off . . .What you said was some bulls--t."

As Andy Cohen and the other housewives suggest that Leakes apologize for "being disrespectful," the Dancing with the Stars celeb seems typically obstinate and fights back. "I said what I said, and I'm not changing on it!"

Watch the fight play out in the video above!
