In episode 13 of "The Real Housewives of Atlanta" that aired on Jan. 27, Kenya Moore took her "frenemy" relationship with Phaedra Parks to another level by mocking her in front of their mutual friends.

Moore, 41, went to the launch party and charity event for NeNe Leakes' shoe line with ShoeDazzle.com wearing a fishnet dress over a one-piece black bikini and a large white hat. The idea was to mock Parks who wore a similar ensemble during the cast members' group trip to Anguilla shown in an earlier episode. Moore revealed her plans to upstage and embarrass Parks as she and her friend were en route to Leakes' party.

"It's going to be live and in living color," said Moore. "You wanna call me crazy?" she said of Parks.

Moore then pretended to be Parks and mocked her Southern accent: "That Kenya girl she must need some medication huh? Cause after she didn't do what I wanted her to do I'm...gonna say anything in the world to just make other people not like her. I do know what defamation of character means honey. And I do know what slander means, because I've been doing that to my good ole friend Miss Kenya."

Moore spoke in her regular voice and pretended to speak to Parks, saying, "Let me just show you how ridiculous you look!"

Moore - dressed in a thong bikini with butt pads attached to her rear and high-heel shoes - visibly upset Leakes upon her arrival at the event. 

"This b**ch just lost it!" said Leakes.

In episode 12 it was revealed that Moore decided to launch her own line of "stallion booty" workout DVDs to compete with Parks' recently contracted "donkey booty" workout DVD. The former friends failed to agree on a fair deal as business partners as decided to in the end work on separate projects. The beef between the two Atlanta residents began after Moore wanted 10 percent of the back-end profits on a new workout DVD she was going to collaborate on with Parks. When Parks refused to give Moore the percentage of sales she requested, the former Miss USA decided to put out a DVD of her own.
