Justin Baldoni Sues Blake Lively and Ryan Reynolds for Defamation

The lawsuit is the latest legal action in a feud tied to the 2024 film “It Ends With Us,” which starred Ms. Lively and Mr. Baldoni, who also directed the film.

The actor Justin Baldoni filed a defamation lawsuit against the Hollywood stars Blake Lively and Ryan Reynolds on Thursday, claiming that they tried to destroy him by accusing him of sexual harassment against the actress and then retaliation against her through a smear campaign.

The lawsuit is the latest legal action in a feud tied to the 2024 film “It Ends With Us,” which starred Ms. Lively and Mr. Baldoni, who also directed it.

The 179-page complaint, filed in the U.S. District Court for the Southern District of New York, named Ms. Lively and Mr. Reynolds, her husband, as defendants, as well as their publicist Leslie Sloane and her company, Vision PR. The lawsuit was filed on behalf of Mr. Baldoni; the film’s lead producer, Jamey Heath; their production company, Wayfarer Studios; and the publicists Melissa Nathan and Jennifer Abel. They are seeking $400 million in damages.

In response to the lawsuit on Thursday, Ms. Lively’s legal team said in a statement, “The strategy of attacking the woman is desperate, it does not refute the evidence in Ms. Lively’s complaint, and it will fail.”

The New York Times published an article on Dec. 21 about Ms. Lively’s allegations against Mr. Baldoni. She claimed in a complaint, filed a day earlier with the California Civil Rights Department, that Mr. Baldoni had initiated the campaign after she accused him of sexual harassment during the shooting of “It Ends With Us.”

The Times report referred to private text messages and emails that Ms. Lively had obtained through a subpoena and that had been included in her complaint.

The complaint alleged that the messages showed Mr. Baldoni and his business partner, Mr. Heath, working with a crisis public relations expert to tarnish Ms. Lively’s reputation because they were afraid the misconduct claims would become public. Ms. Lively sued Mr. Baldoni and others on Dec. 31 in federal court in New York City.

That same day, Mr. Baldoni filed a defamation lawsuit against The New York Times in Los Angeles, accusing the newspaper of relying on Ms. Lively’s “unverified and self-serving narrative.” He repeated some of the claims against the publication in the suit he filed on Thursday.

The Times has said it plans to vigorously defend itself against Mr. Baldoni’s claims against the publication. A Times spokeswoman, Danielle Rhoades Ha, added in a statement on Thursday: “The allegations against The New York Times in this new lawsuit are meritless and recycled from the equally baseless claims in the suit that was filed against The Times in California.”

In his countersuit against Ms. Lively, Mr. Baldoni said the actress had used her star power to hijack “every aspect” of his film and then tried to blame him when her public reputation took a hit during the film’s promotion for how she chose to market it. He accused her of trying to make him “the real-life villain in her story” and of colluding with The Times to “prepare a false and damaging narrative.”

“This is a case about two of the most powerful stars in the world deploying their enormous power to steal an entire film right out of the hands of its director and production studio,” the lawsuit said. “Then, when Lively and Reynolds’s efforts failed to win them the acclaim they believed they so richly deserved, they turned their fury on their chosen scapegoat.”

Mr. Baldoni denied that the alleged sexual harassment of Ms. Lively or the smear campaign against her had happened, and said he was the one who had been the victim of such a campaign.
