Rebel Wilson calls out the star of her own musical The Deb

The feud between Rebel Wilson and cast/crew members attached to The Deb — her directorial debut — has escalated.

Singer/actress Charlotte MacInnes performed at a private party on billionaire Len Blavatnik's private yacht on Friday, May 16 — an event that happened around the 2025 Cannes Film Festival.

Variety reports that Wilson allegedly used the official Instagram account for her film, The Deb, to call out its main star, MacInnes. The billionaire man hosting that party, Blavatnik, had also financed The Deb.

"Charlotte MacInness in a culturally inappropriate Indian outfit on Len Blavatnik's luxury yacht in Cannes — ironically singing a song from a movie that will never get released because of her lies and support for the people blocking the film's release," Wilson wrote, according to the Variety report. "So glad you got your record deal, Charlotte, at the expense of the 300 people who worked on The Deb and really wanna see it released."

Wilson's directorial debut, The Deb, is a yet-unreleased musical about two teen girls in a small Australian town who are preparing for a ball. It premiered at the Toronto Film Festival in September 2024.

Wilson's posts about MacInnes didn't end there. Over the next few days, she also accused the actress of getting more time with one of the film's producers, Amanda Ghost, than other actors and implied that the two were in a relationship. Ghost is married to fellow The Deb producer Gregor Cameron.

Wilson has previously called out Blavatnik on social media.

“Len Blavatnik, please stop funding and protecting Amanda Ghost, Gregor Camero, and Vince Holden,” Wilson wrote in an Instagram story in 2024, per another Variety article. “Clearly, these recent press articles and constant retaliations against me for speaking the truth on my small Australian movie are FALSE. All I did was tell the truth about these absolute fuckwits' — now they launch a bogus defamation suit and bogus articles to inflict further harm."

Ghost, Cameron, and executive producer Vince Holden sued Wilson for defamation in 2024 after Wilson accused them of embezzling funds and sabotaging The Deb's release.

"If my movie gets buried, at least you know why," Wilson said in an Instagram video from 2024, as noted by Variety. She then accused them of "embezzling funds" from the film and "absolute viciousness and retaliatory behavior."

The producers denied the accusations and claimed in their filing that Wilson herself is holding the film hostage "over credits for screenwriting and musical recordings."

Wilson wanted a full screenplay credit on the film but was awarded an "additional writing credit" by the Australian Writers Guild. Screenwriter Hannah Reilly, who wrote the stage musical the movie is based on and the film's script, was awarded sole screenplay credit.

The filing also alleges that Wilson would disappear from the set for extended periods and threatened financiers by "exposing" them on social media.

"Since the beginning, this dispute has been about one thing and one thing only: Rebel Wilson's obsession with taking credit where none is deserved, at the great expense of young, talented women, whom she tears down, all the while, masquerading to be their champion," attorney Camille Vasquez, who is representing the producers, told Variety. "It started with Rebel demanding a writing credit for a film Hannah Reilly wrote, and has morphed into a smear campaign. Rebel Wilson is telling on herself — her latest bizarre outburst of jealousy is her confession."

"What should have been a joyous experience — a dream come true — has now been overshadowed by unnecessary drama. It’s been a heartbreaking and baffling turn of events," Reilly told Variety.

Rielly said that Wilson launched "a series of personal attacks and false accusations, most recently targeting Charlotte," and added that MacInnes is "a phenomenal talent and consummate professional who deserves to be celebrated, not dragged into chaos."
