In part 3 of The Real Housewives of Atlanta season 5 reunion special, another shocking revelation concerning Kenya Moore and Phaedra Parks' husband, Apollo Nida, will be revealed.

Parks will say Moore sent her husband a racy text message after she propositioned him with a sex act.

"Phaedra confronts Kenya about hitting on Apollo," a show insider told InTouch magazine. "Kenya sits there fanning herself while Phaedra attacks."

Parks confirmed the claim exclusively to the magazine, adding that her "husband just asked (Moore) for advice on an acting coach" yet Moore made an inappropriate offer.

"Kenya continued to text him, saying, 'Oh, you look nice,' " while dismissing Nida's texts, according to Parks. She added that Moore at one point "propositioned (Nida) with a sexual act."

Parks said she wasn't worried if her husband would ever cheat on her with Moore because the couple have a "strong marriage," and that it wasn't as if "Kenya revealed something I didn't know."

"There are no secrets," Parks said of her marriage to Nida.

Moore admitted to flirting with Nida but the former Miss USA pageant winner also said, "hitting on and flirting are two different things."

"That man is married. I respect the sanctity of marriage," Moore said. 

Bravo aired part 1 of The Real Housewives of Atlanta's season 5 reunion on Sunday. This year the annual roundup of the cast members with host Andy Cohen will take place over three weeks. When the husbands stopped by the reunion, Moore referenced Nida's criminal conviction. She said in Sunday's episode, "I'm not the one that had sex with a convicted felon."

Moore then shocked everyone with a bombshell after Nida said he didn't care about her: "Maybe you should stop texting me then," she told him.

Part 2 of the reunion special will air on April 14. Part 3 will air on April 21 at 8 p.m. ET
