In June, the Daily Mail reported that insiders said: "Some of the women have already been told unofficially that they'll be returning, so they've been doing everything to make sure they're camera-ready.
"Lydia Schiavello is definitely coming back, that's why she's in such great shape right now - she wants to look her best for the show.
"Jackie Gillies, Gamble Breaux and Janet Roach will most likely be back too, but everyone else is on the chopping block.
"They've been interviewing plenty of potential new Housewives, and are even considering bringing back some old faces like Chyka Keebaugh or Pettifleur Berenger,' the source continued.
This isn’t the first time the RHOM creators have had a cast shake up. Season four saw Pettifleur, Chyka, and Susie McLean replaced by Venus Behbahani-Clark and Sally Bloomfield.
