Kim Zolciak is calling it quits on the Real Housewives of Atlanta, but the drama is far from over.
In a teaser for the Dec. 2 episode, a pregnant Zolciak argues with her fellow Housewives about going on a vacation with them before declaring, “I’m done with this whole thing.” She walks out on them and shoves a camera out of her way in a huff.
Bravo has confirmed to PEOPLE that Zolciak is off Real Housewives of Atlanta after the Dec. 2 episode.
Meanwhile, Zolciak has said on Twitter that she is leaving the Real Housewives for a spinoff. Earlier this year, she starred in her own Bravo spinoff show called Don’t Be Tardy for the Wedding, and Bravo has also confirmed to PEOPLE that a second season, currently titled Don’t Be Tardy…, has been picked up.
So is Zolciak’s seemingly-abrupt exit by choice? Housewives costar NeNe Leakes is fueling the (gossip) fire with her assertion that Zolciak was fired. And now the former friends have taken to Twitter to battle it out.
