She's sharpening her claws.

Kim Zolciak made it very clear when we caught her at LAX yesterday that she doesn't think she did anything wrong in her feud with Nene Leakes, and we'd happen to agree with her. Leakes went OFF on the Don't Be Tardy star and her daughter Brielle recently, calling them "racists" and accusing them of saying her home was infested with cockroaches.

The blonde Bravolebrity takes the racism accusations very seriously, and has decided to hire a lawyer to potentially sue Leakes over the claims.

"She put #KKK on the Instagram post. It’s just that bad. It’s inappropriate. In this day and age, people are dying over racism. I’m on a show with all African-American women, and I’m the only one that’s ever been on the show that’s Caucasian, so it’s the card that sometimes they play, and it’s gross. And I won’t allow it," she told Larry King of her decision to hire legal counsel.

She didn't just hire a lawyer, she told us she hired legal pit bull Marty Singer! Nene better keep her trap shut, or else Kim Z is comin' after her!
