Drama is certain in the upcoming season of The Real Housewives of Atlanta.

An ongoing beef between Kenya Moore and her co-star Phaedra Parks went from verbal to physical during taping for season 6 on Thursday.

TMZ reported on Friday that Parks' husband Apollo Nida, a convicted felon, "violently attacked" Moore's assistant, Brandon DeShazer. Sources told the gossip site the fight stemmed from their ongoing feud over Parks and Moore's competing booty DVDs. Parks and Nido both star in Donkey Booty DVD and Moore later released Stallion Booty Boot Camp.

Nida, however, told a different tale. He told TMZ when there was a fight between two other men during filming and when he tried to break it up, he was attacked by DeShazer.

Fans of the show can recall Moore and Parks became frenemies after they decided to go in business together to release a workout DVD. When they failed to reach a business agreement they could agree on, Moore decided to release her own video.

In an episode during season 5 titled Peaches Don't Grow In Hollywood, Moore had a tiff with Parks when the topic of their separate Booty workout DVDs came up. The former Miss USA shared with everyone her workout video will be called Booty Boot Camp. When Parks was asked the name of her second set of workout DVDs, she did not share it out of concern Moore might steal her idea again.

When they appeared on the season 5 reunion show and the booty DVD feud was discussed, Moore said a pregnant Parks was too overweight to put out workout DVDs.
