A public relations team working for Rebel Wilson allegedly plotted to take down a Hollywood producer by accusing her of sex trafficking … and they might’ve been caught on audio doing it.

A new recording allegedly captures Jed Wallace, the head of a crisis public relations firm, telling publicist Melissa Nathan to claim Amanda Ghost — a co-producer on Wilson’s film “The Deb” — worked as a “madame,” procuring young girls for sex with rich men.

Take a listen for yourself … Wallace suggests exposing Ghost as the “new Heidi Fleiss” … who, of course, infamously ran a Hollywood prostitution ring in the early ’90s.

Bryan Freedman — the attorney representing Justin Baldoni in his ongoing legal case against Blake Lively — is also mentioned during the voice note, first reported by The Hollywood Reporter.

Freedman was Rebel’s lawyer at the time, and if the other names — Wallace and Nathan — sound familiar … that’s because they were also on Baldoni’s crisis PR team that’s currently accused of smearing Lively.

Second verse same as the first?

As for Wilson and Ghost’s case … a now-deleted website called “Amanda Ghost is a Destroyer of Worlds” accused the producer of leaving her failing music career behind by “reinventing herself as a theatrical producer alongside her husband while really procuring young women for the pleasure of the extremely wealthy.”
