*The on again/off again friendship between “Real Housewives of Atlanta” stars NeNe Leakes and Kim Zolciak Biermann is again dead in the water – this time over claims of “prejudice” and children not knowing their place.

In a selfie taken on the plane ride back from their cast trip in Barcelona, NeNe sarcastically referred to her new home as “roach infested.”

“On the way back to the A, I fell asleep thinking about how imma live in my ROACH infested brand new home ?,” she wrote.

The message was cryptic, but the hashtags (“#jealousprejudicebitch,” “#pottymouthtrashychildren,” “#learnedbehavior,” “#donteverspeaktome,” “#thisiswhyiwouldntdoashowwithyou” and “#blackpeopleneedtostopsupportingtheprejudice”) pointed only to one family as the target of her comment – The Biermanns. 

NeNe provided more clarity about the incident while responding to someone in the comment section seeking more info. She confirmed that something “disgusting” and “racist” happened at her home involving Kim and her eldest daughter, Brielle.

“Kim & her daughter oops whole family are racists!,” NeNe responded. “What her daughter did at my home, (which she nor kim were invited to so be clear abt that as well) was pure disgusting, racist, learned behavior etc. children are NOT off limits when you allow your child to talk to adults any kind of way, post disrespectful things on social media and so on. Kim is a calculating bio polar racist with a horrible mouth, who uses black folks for her come up.”

Kim wasn’t even on the cast trip to Barcelona, opting instead to stay stateside and promote the Season 6 return of her family reality series, “Don’t Be Tardy.”

The Barcelona trip was also missing cast members Kenya Moore (who was reportedly disinvited by producers because her husband refuses to be on camera) and Porsha Williams (allegedly sent home early after getting into a fight with Marlo Hampton).

The drama behind all of these dustups will be revealed beginning next month, when “Real Housewives of Atlanta” returns for Season 10 on Sunday, Nov. 5 at 8 p.m. ET on Bravo.
