Blake Lively's 'It Ends With Us' costars Brandon Sklenar, Jenny Slate 'admire her bravery' amid lawsuit

Lively's "It Ends With Us" costars, Brandon Sklenar and Jenny Slate, have publicly expressed their support for the actress.

On Dec. 23, Sklenar took to his Instagram story to urge his followers to educate themselves on the lawsuit that has been filed.

The "1923" star shared a screenshot of New York Times' archive of legal documents and wrote, "FOR THE LOVE OF GOD READ THIS." Sklenar tagged Lively's Instagram account and added a red heart emoji.

"As Blake Lively's castmate and friend, I voice my support as she takes action against those reported to have planned and carried out an attack on her reputation," Slate said in a statement to the outlet. "Blake is a leader, loyal friend and a trusted source of emotional support for me and so many who know and love her."

Slate continued: "What has been revealed about the attack on Blake is terribly dark, disturbing, and wholly threatening. I commend my friend, I admire her bravery, and I stand by her side."

In "It Ends with Us," Slate portrays Allysa, the sister of Baldoni's character and the sister-in-law of Lively's. Skelnar portrays an older version of Atlas Corrigan, a former love interest of Lively's character.

Months after rumors of an on-set feud between "It Ends with Us" costars Lively and Baldoni first surfaced, the "Gossip Girl" alum filed a complaint against the actor for sexual harassment. 

"Ms. Lively was forced to address concerns about Mr. Baldoni and Mr. Heath's misconduct with them directly, and began doing so months before filming began. The concerns she raised were not only for herself, but for the other female cast and crew, some of whom had also spoken up."

According to the documents, some of the demands addressed included no more showing nude videos or images of women to Blake, no more mention of Baldoni's or Heath's previous 'pornography addiction,' no more discussions about personal experiences with sex, no more descriptions of their own genitalia, no more adding sex scenes outside what was in the original script, no more discussions about Blake's weight or deceased father, and more. 

At the time, all parties agreed that the outlined conduct would cease. Despite the agreement, Lively claims in the complaint that Baldoni executed and participated in a "social manipulation" campaign to "destroy" her career and reputation. 

Additionally, Lively denied that she or any of her representatives planted or spread negative information about Mr. Baldoni or Wayfarer, according to The Times. 

Bryan Freedman, an attorney for Baldoni and Wayfarer, told The Times, "These claims are completely false, outrageous and intentionally salacious with an intent to publicly hurt and rehash a narrative in the media."

Freedman added that Wayfarer, and its executives and PR team "did nothing proactive nor retaliated" against Lively. Freedman claims Lively's complaint is "another desperate attempt to 'fix' her negative reputation."

Representatives for Baldoni, including Freedman, did not immediately respond to Fox News Digital's request for comment. A representative for Lively referred to the New York Times article for additional information.
