The Real Housewives of Atlanta certainly know how to bring the drama. The September 10 episode showed the reigning drama queen, NeNe Leakes mock Kim Zolciak after trying on one of her blonde wigs. And according to Kim, NeNe went too far.

“We were just having fun,” NeNe told RadarOnline exclusively at a signing for her book Never Make The Same Mistake Twice at the Eso Won Bookstore in L.A. “Kim said I went too far, but for me it was just about having fun.”

“It’s very hard for me to be friends with someone who is not a real friend,” NeNe said. “If it wasn’t for our interaction on the show, we would have nothing to say to each other.”

In NeNe’s book, Never Make the Same Mistake Twice, she writes about her cast mates- the falling out she had with Sheree, who she says she has known for years. “I never expected to have the falling out with her that I did and on national television,” she writes.

NeNe says, though their lives are taped, certain aspects are off limits. “The master bedroom!” she jokes, before adding, “no, my husband is a very private person and that room is where we relax.”
