Vanity Fair is preparing to publish a deeply reported probe into the complicated relationships between Bravo and its stars, Page Six has learned.

Sources say that a reporter for the famed magazine has been interviewing cast members and other sources around the “Real Housewives” franchise for some six months, and that the piece is slated to appear in the coming weeks.

We’re told the article is expected to delve into the highly demanding work lives of the “Real Housewives” stars, and what they trade in terms of their privacy, their image and even their mental health and relationship with alcohol in order to keep their much-coveted, often highly paid roles.

“[The journalist] is really going deep into what the women go through and what’s expected of them as members of the cast and members of the ‘Bravo family’,” said an insider. “I think it’s going to explain a lot that fans don’t really see or understand about how it really works.”

We hear that, given Vanity Fair’s reputation for rigorous, wide-ranging reporting, there have been some nerves jangling at Bravo’s HQ over the piece. But network insiders say execs are well used to the spotlight being pointed at the high-profile network and that nobody’s sweating it.

Sources say that during their interviews, stars have been invited to reflect on what they have given up to appear on the show, whether its been worth it, and how much control — in retrospect — they feel they have really had.

Meanwhile, we hear the piece also looks into Bravo’s various protocols and guidelines for addressing the well-being of its stars, and to what degree they are effective.

The piece — much buzzed about among the ‘Housewives’ — comes as various former Bravo stars including Bethenny Frankel, Nene Leakes and Brandi Glanville have raised questions about what’s been expected of them and their co-stars during their time with the network.

Last year, Vanity Fair published a lengthy article by heavyweight pop culture writer Anna Peele about the behind-the-scenes culture of British reality show “Love Island,” entitled “How ‘Love Island’ Became A TV Reality of Sex, Fame and Sometimes Tragedy.” (Of course, it’s not yet clear quite how closely the upcoming piece will resemble the “Love Island” story).

Reps for Vanity Fair and Bravo declined to comment.
