Kim Zolciak Biermann Says She and NeNe Leakes Will Never Be Friends Again (Exclusive)

This is one relationship fans shouldn't expect to be repaired at the upcoming 'RHOA' reunion.

NeNe Leakes just went "too far." 

ET sat down with Kim Zolciak Biermann in New York on Wednesday, where she addressed her feud with NeNe Leakes, declaring that while the two have been able to repair their relationship before, this time, Leakes crossed a line she can't come back from.

"Nene and I have been on a roller coaster ride forever, but when you make comments [about being] part of the KKK, it's a little bit too far for me and my family and my husband," Kim shared. 

NeNe and Kim's feud erupted over Instagram in October, when Kim's daughter, Brielle, posted a video about allegedly finding cockroaches at NeNe's house. NeNe then took to social media to slam Kim's family with an explicit message accusing Kim and her family of being racist.

"It's definitely hard to bounce back from, and to put that in somebody's head, it's just foolish and ignorant, but that's social media. You know, she clearly doesn't have somebody telling her to think before she puts it out there. That's evident," Kim said. "She needs a Kroy [Biermann] telling her, 'That's probably not a good idea, sweetie pie. Let's not do that.'"

As for how Kim and NeNe will behave at the upcoming Real Housewives of Atlanta reunion, that's still up in the air. 

"I never know what's going to happen, especially with NeNe. I don't know if she likes me or not throughout the years, so it's always kind of been like a guessing game from day to day," Kim explained. "But you think of what you're going to say and what farewell gift you're going to give to this girl who lost her peach. So, I'd be lying if I said I don't think about it."

"We all get ready for it. We're working out, we're doing our hair, getting our lips done, it's like... we're ready," she added. 

Don't Be Tardy's season finale airs Friday on Bravo and The Real Housewives of Atlanta airs Sundays on Bravo.
