In the sneak peek of the forthcoming Bravo special, Williams calls out Moore for bringing props – including a megaphone and bejeweled scepter – to which the former Miss USA declares: “I will not have you talk over me!”
After a heated discussion, Williams loses her temper and declares Moore "a sl*t from the ‘90s.”
“Shut up, you do not have the right to talk,” Moore says, as Williams jumps up and throws her co-star’s props to the ground.
“I’m going to f—k you up!” Williams yells, getting into Moore’s face.
“Porsha beat the sh*t out of her! Porsha was sick of her implying that she was Kordell’s beard and those toys were the last straw. Porsha is a skinny thing but she was whopping her butt!”
The insider added the security guards immediately tried to break up the fight.
In the drama-filled clip, Phaedra Parks also faces off with Moore.
“You can’t be a housewife, because you can’t find a husband,” Parks says.
Moore quickly brings up Parks’ husband Apollo Nida, who claimed all season that Moore propositioned him for sex.
“I don’t have to look very far because someone’s husband strays,” Moore says, laughing.
