Production pandemonium breaks out as Rachel Uchitel roped into Bravo pilot, while Libbie Mugrabi’s mom rumored to be out already

This show has everything: lies, denials, accusations, in-fighting and cast shakeups. The only thing missing is … the show itself!

Last week, Page Six caught wind of a reality-show-in-the-making tentatively called “Snowbirds,” about a bevy of some of New York City’s most notorious socialites skipping town for Palm Beach when the weather turns cold.

And, while producers haven’t even cobbled together a sizzle reel for the pilot episode yet, we hear that the as-yet-unrealized production is already pandemonium.

We hear that Jane Scher, the mother of colorful divorcee Libbie Mugrabi , may be out before she was ever really in, and Tiger Woods’ former mistress is joining the cast — even though she swears she hasn’t!

The infamous Rachel Uchitel, who has been trying to ease her way into the Bravolebrityverse for years , may finally get her wish.

Sources told us Uchitel was spotted shooting several scenes with prospective castmates over the weekend — including a “Love from Palm Beach” cocktail party at Camila Webster Gallery. Uchitel also shot scenes at cast member Cindy Guyer’s “half birthday” party on Sunday, we hear.

But the “Miss Understood” podcast host told us that, even though she “was at the party where they were filming for the weekend,” she is “absolutely not on the cast.”

Meanwhile, a production source told us it’s actually a little bit of both: Uchitel sparked their interest after she showed up to all the weekend events, and then they decided to shoot a subsequent sit-down interview with her. Now exploring the possibility of her joining the show.

Scher, on the other hand, “was nowhere to be found in Palm Beach,” adding to speculation that she’s not participating in the show after all.

“She did not film. Nobody would film with her. These are substantial people and, no one wants to be associated with her,” a source told Page Six.

But Scher responded, “No comment, and whoever told you that is lying, and it’s not the truth,” when we reached out on Monday.

(So to recap: the cast member everyone says is in says they’re not in, and the cast member everyone says is out says they’re actually in. Got it?)

She then added, “There’s no show! There’s no show! There is no show, and whoever is leaking this is full of sh-t! If I were you, I would stop writing about the ‘Snowbirds,’ because it’s not true! This is all bullsh-t!”

Hopefully things will become a little more clear to Scher because our production source added, “Jane’s definitely not out. We’re shooting with her and others.”

In the meantime, an insider confirmed Sharon Bush, a former in-law to the Bush dynasty, was on the list of “substantial people” who were shooting the pilot, but her spokesperson, R. Couri Hay, told Page Six on Monday, “She was never going to do this show.”

“She’s focused on the nonpartisan Museum of Democracy, not doing a reality show,” he said.

As an example of the “sort of thing she does” he pointed us to Fashion 4 Development organization, which will honor Bush and her daughter, Lauren Bush Lauren, at their annual First Ladies Luncheon on Sept. 24, which is held during the 79th session of the United Nations General Assembly.

But if she’s not doing it, it sounds like someone needs to tell production. Our insider told us Bush was never meant to be a main character, but, “She’s not definitely out.”

We were previously told “Snowbirds” is not going to be “The Real Housewives of Palm Beach.” An insider described the show as “more like a reality ‘Palm Royale,'” referring to Apple+TV’s hit comedy series starring Kristen Wiig.

Guyer, Gale Brophy, publicist Anna Rothschild ( who is no stranger to headlines) , and Palm Beach couple Guy Clark and Harrison Morgan are still on board, we’re told. Rothschild co-hosted Saturday’s “Love from Palm Beach” cocktail party with Webster.

Sources previously told us Harry Dubin, an unofficial cast member of “The Real Housewives of New York,” was not signed on for the show, but he didn’t shy away from the cameras all weekend, we hear.

Reps for Bravo did not comment.
