Ramona Singer: All the N.Y.C. Housewives (Plus Bethenny!) Returning Next Season

"Bethenny will come on a little bit. We need a Bethenny moment," Ramona Singer tells PEOPLE about the show's upcoming fourth season, adding that the other women – Alex McCord, Kelly Bensimon, Jill Zarin, Sonja Morgan and Countess LuAnn de Lesseps – "have been renewed."
In June, Frankel said she didn't see herself returning as a Housewife unless there were a few key changes. De Lesseps at the time also said she was unsure about her future with the hit Bravo show.
But now it looks like the seven women won't be alone.
"One or two new castmates" will be joining the crew, says Singer – but that doesn't necessarily mean there will be more drama.
"I think we're going to have some good energy," she said on Sunday while sitting front row at the Rebecca Taylor show during New York Fashion Week. "And I'm not going to let any bad energy come into the show."
Bravo, meanwhile, wouldn't comment on any casting discussions.
"No decisions have been made for the fourth season," a Bravo rep says.
