During last night’s March 9 episode of Real Housewives of Atlanta, we watched as Porsha Williams took on an unlikely critic: Peter Thomas. Cynthia Bailey’s husband took Porsha to task about her recent split from husband Kordell Stewart — just days after he had a secret meeting with Kordell himself. And when Porsha tried to defend herself, she only made things worse.

During the whole crew’s trip to Mexico, Peter brought up his chat with the former NFL player, saying that Kordell fingered Porsha’s family and their meddling as the cause of the split. To that, Porsha responded that, “what I can say is that how our relationship changed and how it became public was by choice and it was for him… I told him that I had a plan for us, and that my plan was to be the ideal couple. And that whatever was in his past that was nasty, that hurt him, those rumors, all of that … that I would help him erase that.”

Of course, this shocked everyone at the dinner, including Peter who accuses her of making it sound like she ran a “PR campaign” for their marriage. But even many months later, Porsha did not appreciate Cynthia’s man saying that, and she made it known on Twitter last night.

“You know same way your wife has to convince people you ain't taking her money!! #RHOA #thatsPR,” Porsha tweeted. Oo, shade!

We didn’t expect Porsha to loop Cynthia in on this mess, but homegirl clearly isn’t messing around. For those unacquainted, Peter and Cynthia have seen their share of public criticism over their marriage, with many accusing the Atlanta businessman of freeloading off of his successful supermodel wife.

Neither party has responded to Porsha’s slam just yet, but we’ve got a feeling Cyn won’t be taking too kindly to that comment.

Were you surprised to see Porsha lash out at Cynthia and Peter like that? Whose side are you on? Tell us in the comments below.
