Things are getting even uglier between Kim Zolciak-Biermann and her parents. On the most recent episode of Bravo’s Don’t Be Tardy, the reality star — who hasn’t spoken to mom Karen in six years — made it clear that their relationship is over.

“My children, I will always be in their life,” the 39-year-old said. “But my mom? I will not let her back into my life, let’s just be clear.” At one point, Karen even sued her daughter for grandparent visitation rights. “My mom and I have always butted heads. She’s kind of tormented me for many years,” Kim explained. “Marrying Kroy, you would think it would get easier but it’s actually only gotten worse. It’s one thing messing with Kroy and I, but when you’re messing with my children, it becomes a whole different ballgame for me.”

The episode aired just days after Life & Style spoke exclusively to Kim’s father, Joe Zolciak, after it was revealed that the Real Housewife of Atlanta had proposed a TV reunion with him. “I have no plans to speak to [Kim] ever again,” Joe said, adding that if the mother-of-six did want to see him, “she would have to crawl up my driveway on her hands and knees and apologize to my wife.”

Things got heated between the duo after Joe publicly slammed his daughter’s decision to keep their dog Sinn after he bit her five-year-old son Kash. “If I had a dog that attacked one of my children, it would be gone,” he recently told In Touch. “[If Kim and Kroy] want to keep the dog that bit my grandson in the face, then shame on them! You don’t know if it’s going to happen again.”

Kim responded to her dad’s comments in a tweet, writing, “It’s disgusting and sad. My parents haven’t been a part of my life or [the kids] for 6 yrs. They have never met Kash or our dog. I do know they will do anything for a dollar.”
