"The show will follow her planning her wedding to Jason Hoppy," a "tipster" told The Post.
Bravo had "no comment" when contacted by The Post, however the newspaper reported the new series will be titled Skinny & The City -- a combination of the titles of HBO's popular Sex and the City drama and Naturally Thin: Unleash Your SkinnyGirl and Free Yourself from a Lifetime of Dieting, the book Frankel released in March.
Last week, the 38-year-old Frankel was spotted wearing a diamond ring reportedly given to her by Hoppy, whom she's been dating for the past eight months.
"I can confirm Bethenny and Jason are in love and plan on getting married," her rep coyly told Us Weekly at the time. "I guess this is the starter ring."
Although the bling Frankel was sporting might not be an official engagement ring, a source close to the couple told Us that a proposal is "on the way."
Bravo renewedThe Real Housewives of New York City for a third season last week and began casting for additional housewives as Frankel, Alex McCord, Jill Zarin, LuAnn de Lesseps and Ramona Singer are all reportedly still unsigned for the new season.
Kelly Bensimon -- who joined the show for its second season -- is reportedly the only woman who has currently signed on for the new season.
"We're in discussions for next season," McCord told the New York Daily News at the time. "Let's put it this way: We're headed to Australia to promote the show. And we wouldn't be doing that if we weren't ready for next season."
The reason for the holdout, according to a network insider, is money -- a claim that was subsequently confirmed by Zarin, who said the reason why all five of the show's original women remain unsigned is due to a salary dispute centered on its stars being compensated equally.
