told Cynthia Bailey's husband, Peter Thomas, to stop acting like "a bitch" on Sunday's The Real Housewives of Atlanta"
, and the word and its delivery was nearly enough to break up a close friendship.
After Thomas and Gregg Leakes went loco in Mexico
, and NeNe inserted herself into the ongoing masquerade ball
battle – telling Thomas that he needed to stay out of the women's business – the longtime friends went after one another.
"The way he came at me I didn't really appreciate it," Thomas told his wife after everyone had returned from the trip. "He told me he was giving me a pass … was he actually gonna have a fistfight with me?"
"I do not feel bad for addressing her husband because he's always addressing everybody else," NeNe told her own husband. "I did feel like he was a bitch. I did."
"Bottom line is friends don't go around calling friends bitches," a calm yet upset Bailey said. "Right is right, and wrong is wrong … I'd rather not be friends with them if that is the case."
The couples met for dinner (read: vodka tonics) to address their fight, and it was more than awkward in the beginning.
"Why is it feeling like a first date?" Bailey, 46, asked.
"I just want to put a line real deep in the sand that we respect each other," Thomas asked at the dinner.
"I just called a spade a spade," NeNe replied. "I was really just trying to say you were acting
like a bitch. So I can't apologize for that."
word is very provoking," Bailey told her friend.
"If you were to call me a bitch, it would crush me," Gregg Leakes said, easing the tension. "I'd like to extend my hand to you and my deepest sympathy … we're friends."
"My relationship with Cynthia is the most important," NeNe, 45, admitted as the four made up.
word also played a prominent role Sunday, as Kenya Moore
hired a parenting coach to teach her how to handle a potential baby.
In this case, Moore, who is considering having a child, was given a baby doll to feed, burp, diaper and name.
"I don't want to name it Apollo because I don't want it to go to jail," Moore, 42, joked. "I don't want to name it Porsha because I want her to find the United States on a map, and I don't want to name it NeNe because I want her to be born with hair on her head."
