The "Real Housewives of Atlanta" is about to get real sizzling, as two of the housewives have begun a feud based on social media allegations about sex.

Kim Zolciak-Biermann, following last Sunday's episode, has claimed that Kandi Burruss and her husband are swingers, or people who routinely have casual sex with others. These allegations were done on-camera during the said episode and were taken to Twitter by the two housewives afterwards.

"I'm sick of these b— lying on me," Burruss wrote on Twitter. "@KimZolciak I have NEVER wanted you," fumed the enraged 41-year-old housewife.

To this, Zolciak replied, "If anybody is lying it's you @Kandi. You and your husband are full on swingers f— all kinds of girls and can NEVER admit it. And b— if it weren't for me there would be no house. Remember I built this house!" she continued, signing things off with a kiss emoji.

This feud also stemmed from Zolciak's comments towards Burruss on the same episode regarding the latter's feud with Porsha Williams. Since then, tension heated up a lot, leading to the social media outburst between the two housewives.

While Zolciak claimed that she understands why Burruss would not forgive Williams for whatever she did, Zolciak also retracted that Burruss herself was not that innocent or free of fault. Zolciak then claimed that Burruss herself even propositioned her to perform oral sex on each other, to which Zolciak rejected and even shunned Burruss, where she stated that under no circumstance that she would let Burruss do that to her.

Zolciak also stated that she did not claim those just to be mean and that she had the truth in mind when she spilt the supposed secrets about Burruss and her husband. That said, it is was not clear who was telling the truth and who just trying to be mean to the other.

More drama and fights between the two are expected to happen in the next episode of "Real Housewives of Atlanta" which airs on Sunday, Jan. 21, at 8 p.m. EST on Bravo.
