When you mess with one, you mess with them all! Kim Zolciak's adorable blended family is as tight-knit as it comes, so it would make sense that her oldest daughter Brielle Biermann came to her mama's defense in the ongoing feud with her Real Housewives of Atlanta co-star Kenya Moore. Brielle took to Twitter to let everyone know how she really feels about her mom's enemy.

"Kenya is a dumb ugly evil b—-," the 20-year-old wrote, and one fan told her to mention Kenya's Twitter handle so Kenya could see her tweet. But Brielle was confident that Kenya would eventually see it and responded, "I don't need to! She stalks me and my mom."

It seems like Kenya did read Brielle's tweet, and the 46-year-old threw some subtle shade back at her. Kenya posted a photo of herself looking fabulous in a white dress standing in the front of the front door at her home, Moore Manor. She captioned the shot, "Everywhere you look there are haters…don't let them dull your shine or steal your joy."

After months of rumors, Kim finally confirmed that she will be making her return to RHOA on the upcoming season, and Kenya had a lot to say about it. “Yeah, Kim is coming back — yes, Kim needs a check so Kim will be back,” Kenya said during an interview with The Breakfast Club back in May. She also suggested that Kim’s RHOA spinoff show Don’t Be Tardy wasn’t pulling in successful ratings, “The checks were tardy, so she’s over here trying to catch ours."

But Kim did not let her get away with that snide comment, and her clapback was epic. “Hmm this sh– is funny!!” the 38-year-old wrote. “Sweetie don't try and come for me so you can have a story line for next season.”
