The Real Housewives of Atlanta season 6 reunion special part 3 will be airing Sunday, May 4, at 8 p.m. on Bravo TV.

In the third and final part of the RHOA season 6 reunion, Kandi Burruss will be confronting Nene Leakes over comments made about her mother, Momma Joyce. In a preview video, Burruss tells Leakes: "I tried to keep everybody at a certain level of respect – I try not to speak on your kids, your parents, your husband, and I try not to address anything that hasn't been talked about on the show." She then points to Leakes and says, "But you do it all the time. "

When Leakes asks what she wants her to do about it, Burruss says, "you could apologize."

Fans of the RHOA reality show would be curious as to which castmembers would be returning for season 7. The future of Porsha Williams is unknown after her violent altercation with Kenya Moore in Part 1 of the season 6 reunion.

Earlier this month, Kenya Moore said she may not be returning to the show, but that too has not been confirmed by the network's officials as of yet.

Meanwhile, there are rumors that original castmember Sheree Whitfield may be returning. According to Atlanta blogger Funky Deniva, Whitfield, who starred for four seasons on the show before her departure, will be back for Kandi Burruss' wedding special which is set to air in June. "By the end of Kandi's wedding night, Sheree was filming full on scenes with Derek J and Lawrence," wrote Funky Deniva.

Whitfield did not confirm the news, but she wrote: "It's been an awesome day! Things r looking good.."
