• Last summer, journalist Kjersti Flaa shared a video of what she called a "nightmare" interview with Blake Lively.
• Lively has accused "It Ends With Us" co-star Justin Baldoni of orchestrating a smear campaign against her.
• Flaa was mentioned in a legal complaint but denied being part of the alleged smear campaign.

Kjersti Flaa, a Norwegian journalist who helped fuel a backlash against Blake Lively in the summer, denies being part of an alleged smear campaign against the actor.

In August, Lively was promoting her latest movie "It Ends With Us," which was overshadowed by rumors that she and her co-star and the film's director Justin Baldoni had fallen out. It culminated in a widespread backlash against Lively.

Lively alleged in a legal complaint filed Friday that Baldoni, his publicists, and the production company orchestrated a smear campaign against her. She accused his team of enacting a "multi-tiered" plan to "destroy" her reputation to stop complaints she made about Baldoni's behavior on the film's set from being made public.

Bryan Freedman, an attorney for Baldoni and his company Wayfarer Studios, said in a statement that the claims made in Lively's complaint were "categorically false."

The lawsuit also briefly mentions a video Flaa shared on YouTube at the height of the backlash, titled "The Blake Lively interview that made me want to quit my job." The video, which went viral in August, shows Lively giving a hostile response after Flaa congratulates her on her "little bump" in a 2016 interview.

On Saturday, Flaa denied claims she worked with the team Lively alleged carried out the smear campaign after the lawsuit and a New York Times article connected her to it.

"This is what I do for a living. I would never accept money to jeopardize my integrity as a journalist," Flaa said in a YouTube video.

Flaa said she wasn't aware of the backlash against Lively and posted the video because she didn't like "It Ends With Us," had a bad experience with Lively, and "had enough of Hollywood."

"I know nothing about Justin Baldoni. I know nothing about his PR team, and I definitely would never work with a PR team under any circumstances to put hate out there on the internet against someone or to smear someone. I would never ever do that," Flaa said, adding that she thought the messages sent by members of Baldoni's team used in the lawsuit were "disgusting."

Flaa said Lively should take accountability for her "tone-deaf" promotion of "It Ends With Us," such as not talking about the domestic violence element of the story, which fueled the backlash over the summer. The film is about a florist who ends up in an abusive relationship.

Business Insider reached out to reps for Lively and Baldoni but didn't hear back.

In Lively's lawsuit, she said that the cast was contractually obligated to follow a marketing plan created by Sony Pictures Entertainment, the distributor of the film, to avoid talking in a way that made the movie appear "sad."

Flaa ended the video by inviting Lively to her show.

However, by Monday, she had changed her tune when she posted another video in which she accused Lively's team of trying to undermine her credibility to rebuild the actor's reputation.

Flaa said she has received hate mail and accusations that she was being paid to "smear other women."

"I just don't want to be a part of this whole mess. U never asked to be a part of it," she said. "So please stop spreading lies about me."

Representatives for Lively and Baldoni did not immediately respond to a request for comment from Business Insider.

An attorney advising Robert F. Kennedy Jr. is slamming a New York Times report last week that claimed the Trump HHS secretary nominee sought to revoke the Food and Drug Administration's (FDA) approval for the polio vaccine.

"Contrary to hysterical media reports that the petition sought to make sure no polio vaccines would be available, the scope of the petition was quite narrow," Aaron Siri, a close RFK Jr. adviser and partner at Siri & Glimstad LLP, told Fox News Digital. "It simply asked the FDA to require a proper trial for licensure for children of a novel polio vaccine."

The New York Times reported Friday that Siri is "waging a war" against all vaccines, but Siri said the report "falsely claimed the petition sought to eliminate" the polio vaccine, "as if there is only one, and that our client sought to leave Americans without the choice to get vaccinated for polio."

"In reality, the petition sought to ensure the safety of one of the six existing licensed polio vaccines that we inject into our children three times before their first birthday," he said.

The report came just days before RFK Jr. headed to Capitol Hill this week to meet with Senators, seeking support for his HHS confirmation.

The petition, filed in 2022 on behalf of the Informed Consent Action Network (ICAN) and not as an individual action by Siri, urged the FDA to suspend the polio vaccine IPOL for infants and children. ICAN's request stems from concerns that IPOL, licensed in 1990 by Sanofi, was approved based on pediatric trials that, according to the FDA, evaluated safety for only three days after injection.

This is not the traditional polio vaccine developed by Jonas Salk or Albert Sabin that many people are familiar with, Siri added. Instead, it is a product utilizing a different technology, where the polio virus is grown on monkey kidney cells that have been genetically altered to replicate indefinitely, similar to cancer cells. Traces of these cells are present in each vaccine dose.

Another petition filed on behalf of ICAN in 2021 addresses 13 childhood vaccines containing aluminum adjuvants. According to the petition, a peer-reviewed study found discrepancies between the aluminum levels in these vaccines and the amounts listed on their FDA-approved labels. The petition calls on the FDA to verify and publicly release documentation proving the accuracy of the aluminum content or halt distribution until resolved — an issue critics say should not be controversial for products injected into infants.

"Currently, political labeling (pro-vaccine, anti-vaccine) is inadequate to encompass the realities of medical ethics, regulatory capture, and the influence of corporate money on health policy," Siri said. "We must be able to raise valid questions about vaccine safety, efficacy and policy without fear that any deviation from the mantra 'safe and effective' will be smeared with epithets and outrage."

In the days since media outlets have reported about Siri's petition, both Trump and RFK Jr. have said they support the polio vaccine, without specifying which one. RFK Jr. has expressed his skepticism of some vaccines, while supporting the use of others, in interviews during his 2024 presidential campaign run as part of his "Make America Healthy Again" (MAHA) slogan. 

"Mr. Kennedy believes the Polio Vaccine should be available to the public and thoroughly and properly studied," Katie Miller, the transition spokeswoman for Kennedy, said in response. 

Meanwhile, Trump said "everything should be looked at," adding that he's a "big believer in the polio vaccine," during a Mar-a-Lago press conference Monday morning. 

Fox News Digital reached out to the New York Times for comment but did not receive an immediate reply.
