Kelly, 43, and Tamra, 51, were caught on camera yelling at one another while their RHOC costar Shannon Beador stood in the middle.
The Cut Fitness owner at one point threw her hands up in the air and screamed "You said it on camera!" to Kelly.
“This all goes back to when Tamra was caught talking s**t about Kelly and telling everyone that Kelly pushed her mom down the stairs," a RadarOnline.com insider claimed.
Kelly denied the situation ever happened. "Tamra told her that she discussed it on the show which is the only reason she brought it up," the insider continued.
“And Shannon tried to mediate the situation in Miami because it is the first time that Tamra and Kelly have seen each other.”
Kelly has had enough of her longtime RHOC costar. "Kelly cannot stand Tamra and is so fed up with Tamra and is sick of her being a two-faced b***h who can do whatever she wants and get away with it," the Radar insider claimed. "She just thinks that Tamra has done this too many people and it’s time for her to go.”
