It all started when Kim decided to "poke the bear," as Cynthia Bailey put it, by asking Kenya incessantly about her surprise marriage to Marc Daly, who Kim insisted didn't exist.
"I just asked where your husband was," Kim said.
"Where's your dick?" Kenya replied. "You clearly have a hard on for me. Worry about your life and the daughter you pimp out for John Legend tickets. See whose dick she'll suck for John Legend tickets, bitch."
"Let me tell you something, bitch, 'cause you will not talk about my f-cking daughter!" Kim yelled back as she had to be physically restrained from lunging at Kenya. "That's where you crossed the motherf-cking line! You don't talk about my f-cking daughter!"
Kim went from angry to hysterical in a matter of seconds and ended up throwing a glass in Kenya's direction. Kim's husband, Kroy Biermann, came rushing to the scene to rescue his wife from -- well -- assaulting Kenya.
"Take that trailer park bitch outta here," Kenya said as Kim was being escorted to Kroy's car.
"There are very few things that get me this f-cking mad," Kim said to Kroy. "Kroy, please let me go back in there to say something."
"Hell f-cking no," he said. Shereé Whitfield, who was accompanying the couple to their car, agreed.
"Right now, I just need to get Kim away from Kenya," Shereé said. "She's got about 17 kids, and them kids need their mom at home and not in jail."
Kenya's blow was in reference to a tweet Kim posted back in May, jokingly asking Chrissy Teigen who her daughter, Brielle Biermann, had to "blow" in order to meet John Legend at his Atlanta concert. Chrissy ended up replying with this:
Plz don't blow anyone it's not that good of a show. Jk it's good but I'll get you tix without the oral
Kim later explained to Bravo cams, "You're talking about Brielle, you don't know my relationship with Chrissy. I'm free to tweet whatever the f-ck I want. It's not for your eyes, dumb bitch, so I don't even know why you're talking about it. I don't know what this bitch is doing except walking around pretending she got f-cking married."
NeNe then said in her confessional, "I'm trying to be calm, honey, and be a gracious host. I didn't hear everything, but I think Kim egged Kenya on. I believe that kids are off limits, but you can't be posting stuff about your own child sucking dick and then be mad somebody else said she sucked a dick. Honey, the music ain't that great. I listen to it on the iPod."
