In a preview for the Hair Stylist’s Tell All special airing this Sunday, Derek J remembers the fight on the tour bus to Miami that ultimately ended NeNe Leakes and Kim Zolciak’s friendship.

Although the argument took place over a year ago, it’s still hard to watch NeNe call Kim an “immature dumb blonde,” and hear Kim fire back, “You’re a dumb bitch.”

Even though the fight was dramatic, Derek J admits, “I don’t know why Kim was so surprised by that, I mean, she gets threatened all the time.”

“NeNe’s either gonna slap her, choke her, pull her, or push her down.”

“Sheree’s gonna pull her hair,” Miss Lawrence interjects with a laugh.

“Is this racism against a white woman?,” Derek J asks.
