Tonight, Bravo will conclude the three-part series to The Real Housewives of Atlanta season 5 reunion special and it will end with a bang.

In part 3, a shocking revelation concerning Kenya Moore and Phaedra Parks' husband, Apollo Nida, will be made after the show's host, Andy Cohen introduces the wives' husbands to the set.

When Cohen revisits an earlier episode when Moore flirted extensively with Nida during a couples' trip to Anguilla, the former beauty pageant mentioned his criminal conviction.

In the preview clip for Sunday's episode, Moore insults Parks and says, "I'm not the one that had sex with a convicted felon."

After Nida responds to the comment and says he didn't care about Moore, she drops a bombshell and tells him: "Maybe you should stop texting me then."

Parks will then reveal that Moore sent her husband a racy text message where she offered him sex.

An insider revealed spoiler details about Sunday's episode starring the husbands at the reunion.

"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,'" Parks told InTouch. 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 the magazine to flirting with Nida but explained that "hitting on and flirting are two different things."

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

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