In season 3 Episode 18 of The Real Housewives Of Atlanta, Kenya Moore will have an unexpected run-in with her ex-boyfriend Walter Jackson at cast mate Kandi Burruss' housewarming party tonight when the series air.

"By now everybody knows that Walter is here with a date but Kenya," model-turned-entrepreneur Cynthia Bailey tells the camera in her confessional at the party, according to a preview of tonight's episode. "Everybody waiting with the popcorn in their hand waiting for the 'show' to start, I am just really feeling uncomfortable about this whole thing," she added.

"I guess I gotta separate these two before they twirl out of control," Burruss says about the former couple.

Jackson was already at the party with his date when Moore arrived. Burruss, out of concern that Moore might get upset about it, brought the subject up thinking Moore was already aware that Jackson was there.

"I really gotta tell you because I'm sure you're feeling some kind of way because Walter is here or whatever..." Burruss tells Moore.

"You said Walter's here?" Moore replies, visibly disturbed by the news. Burruss is shocked by Moore's reaction and begins to laugh about it .

"It's not funny, he's showing up to every event that I go to and I don't have my security," Moore says. "And its not gonna happen like this."

"Well I don't think he's gonna do anything," Burruss tries to explain,  then Moore walks off visibly upset.

Porsha Stewart will have a heart-to-heart conversation with her husband Kordell about what the rest of the castmates said about him during their Las Vegas trip. Stewart would not go to a strip club with the rest of her castmates in last week's episode because her husband told her not to.

After Stewart tells her husband that her friends think he is too controlling, he told her that her friends "don't understand is you respect what you have."

"I'm in control in general, I'm a man, I have a responsibilities," he added. "I'm in control, but I'm not controlling," he explained about their marriage.
