The ladies of the "Real Housewives of Atlanta" cast are prepared to clear the air once and for all during the upcoming reunion special of the hit Bravo reality TV series. Phaedra Parks' drama with her former best friend Kandi Burruss that stemmed from a bad business deal between Parks and Burruss' husband Todd Tucker came to a head when Burruss fiercely defended her man.

Throughout the eighth season, Parks and Tucker bickered about a pregnancy workout DVD that Parks hired Tucker to shoot and edit for her. Tucker maintained that he finished the project and still had not been paid, but Parks disagreed. She said Tucker left the project unfinished - which is why she withheld his payment.

In a sneak peek for the upcoming reunion special, Parks explains that in the video production business, projects are paid for in segments, and she told Tucker he would get paid once the project was completed. As of now, Parks says Tucker is paid off ,but Burruss interrupts and says they only settled their business just last week.

"That's convenient," cast mate Kenya Moore says, throwing subtle shade at Parks.

"Whatever, honey," Parks responds. "He has been paid all his money, all the checks have went through and I still don't have a video that I can commercially release."

Reunion special host Andy Cohen brings up DonJuan, one of Burruss' employees. DonJuan confronted Parks and cast member Porsha Williams when he overhead them discussing the drama with Tucker in a previous episode, and Burruss defended DonJuan's actions.

"My team - they go hard for me and I go hard for them," Burruss says.

Parks says it's unprofessional for Burruss to allow her employees to badmouth her friends, and Williams accuses them of being a clique.

"He just wanted camera time," Williams chimes in. "We were having a conversation and it didn't escalate until he made it personal. It just went below the belt for just no reason at all and that's why I felt like it's a Kandi Koated gang."

"If you're talking about my husband and you're saying different things about what he did with the video and try to make it seem like he did something wrong, then you're downing my man business-wise," Burruss says, accusing them of spreading a bad impression of her husband.

"You can discuss it if it's true," Burruss says, her voice getting louder. "But if it ain't true, that's when you can't discuss it. Don't go in, let have and it not be true. If I go in, let have- i t's gonna be true!"
