The third and the final part of The Real Housewives of Atlanta reunion aired Sunday and Kandi Burruss and Nene Leakes got into a screaming match.

The two women, who were seated next to each other on the couch got into a heated argument after addressing something Leakes wrote in her Bravo blog back in February, when Buruss was shocked that she walked away from a fight with Marlo Hampton.

"Kandi, you have never seen me walk away from a fight and you have never seen me physically fight either have you?" NeNe wrote at the time. "My son was at this event, and as much as I would like to be Mama Joyce and take my shoe off and hit somebody or drag someone down the street, I would never stoop so low to the gutter with my son around, so you are right!"

During the show, Burruss raised her voice and pointed her finger at Leakes for bringing up her mother's name. 

"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."

Even after host Andy Cohen suggested that Leakes should apologize to Burruss for "being disrespectful," she refused to do so, saying, "I said what I said, and I'm not changing on it."
