Money complicates everything! After clashing throughout The Real Housewives of Atlanta's eighth season over payment for production on the Phine Body prenatal workout video — plus much deeper tensions in their friendship — Phaedra Parks and Kandi Burruss battle it out in the Bravo series' reunion on Sunday, March 20, as seen in Us Weekly's exclusive sneak peek.

Host Andy Cohen asks Phaedra, 44, to explain the situation, and the entertainment lawyer responds by saying that it is customary in the industry to pay some money up front but withhold full payment until the project is completed. She has maintained that Kandi's husband, Todd Tucker, hadn't finished post-production work on the video.

"He has been paid all his money, all the checks have [gone] through and I still don't have a video that I could commercially release," Phaedra says.

Porsha Williams accuses Kandi, 39, and her employees of forming a "Kandi-coated gang," but Kandi says that her costars opened themselves up to criticism by claiming that her husband hadn't fulfilled his responsibilities.

Phaedra fires back, "At the same time, Todd was in there talking about me to Peter [Bailey], so it's like, you can't have it both ways."

Watch the tense scene in the video above.

The Real Housewives of Atlanta airs on Bravo on Sundays at 8 p.m. ET.
