Rebel Wilson vs. Sacha Baron Cohen: Actress may have signed ‘a PR deal with the devil,’ expert

Rebel Wilson and Sacha Baron Cohen's back-and-forth over the actress' upcoming memoir is another example of the "never-ending victim marketing" era we live in, according to one brand expert.

"To some extent, this is just part of literary PR, i.e., chumming the waters with juicy tidbits to generate media coverage ahead of the launch," branding expert Doug Eldridge told Fox News Digital. "However, there is a tipping point, where the person on the receiving end of these book-baiting allegations, must act in a sense of self-preservation — whether personally or professionally — and hire the appropriate team to guard against inaccuracies that can quickly amount to defamation."

Wilson called out the "Borat" star by name as the "a--hole" she wrote about in her upcoming memoir, "Rebel Rising." The "Pitch Perfect" star chose to name Cohen after he allegedly "bullied" her with lawyers and PR.

"I will not be bullied or silenced by high priced lawyers or PR crisis managers," Wilson wrote on her Instagram story Sunday. "The ‘a--hole’ that I am talking about in ONE CHAPTER of my book is: Sacha Baron Cohen."

Representatives for Wilson did not immediately respond to Fox News Digital's request for comment.

The actress first revealed she had written about an "a--hole" with whom she previously worked without naming Cohen in an Instagram post shared on March 15.

"When I first came to Hollywood, people were like, ‘Yeah I have a no a--hole policy. Means like, yeah I don’t work with a--holes.' I was like, ‘Oh yeah, that sounds sensible, logical,'" Wilson said in the shared video.

"But then it really sunk in what they were meaning by that — older people in the industry — because I worked with a massive a--hole, and yeah, now I definitely have a ‘no a--holes policy,'" she further explained. "The chapter on said a--hole is chapter 23. That guy was a massive a--hole."

A representative for Cohen slammed Wilson's accusation as "demonstrably false."

"While we appreciate the importance of speaking out, these demonstrably false claims are directly contradicted by extensive detailed evidence, including contemporaneous documents, film footage, and eyewitness accounts from those present before, during and after the production of 'The Brothers Grimsby,'" the representative told Fox News Digital.

Wilson and Cohen starred together in the 2016 film "The Brothers Grimsby" as a husband and wife of nine kids. Later, Wilson accused Cohen of "harassing" her on the movie set during a radio show interview, according to Variety.

"Every day he’s like, ‘Just go naked. It will be funny. Remember in ‘Borat’ when I did that naked scene? It was hilarious,’" Wilson said, the outlet reported. "On the last day, I thought I’d obviously won the argument, and he got a body double to do the naked scene."

Cohen allegedly told Wilson to "stick [her] finger up [his] butt" while filming the last scene, despite the move not being included in the script.

"Look, I’ll just pull down my pants. You just stick your finger up my butt. It’ll be a really funny bit," he allegedly said.

The "never-ending 'victim marketing'" era is focused on creating sympathy with the accuser, according to Eldridge.

"We are living in an era of never-ending ‘victim marketing,’" he explained to Fox News Digital. "It's the idea that in order for someone to be sympathetic — much less empathetic — they must somehow be the victim, while someone else must be equally vilified."

"The idea is not to engender synergy with the target audience, but rather, sympathy," he continued. "The sad thing is that often times, these claims are taken out of context, or fabricated altogether. If you have to put somebody down in order to lift yourself up – whether to sell a book or a life coaching seminar, then maybe you didn't have much substance to offer in the first place."

He added: "All in all, damaging another in hopes of improving yourself is like signing a PR deal with the devil; the benefit is short term, while the end result is both certain and permanent."
