Blake Lively sues ‘It Ends With Us’ co-star Justin Baldoni for sexual harassment, campaign to ‘destroy’ her reputation

They starred in “Ends With Us,” but their legal battle is only just beginning.

Blake Lively has filed a bombshell lawsuit against co-star Justin Baldoni alleging he sexually harassed her on the set of their hit film, TMZ reports.

According to the legal docs, the actress further accuses Baldoni — who also served as the director of the film — of “a coordinated effort to destroy her reputation” following the movie’s release.

She says the smear campaign caused harm to her business and led to her family experiencing “severe emotional distress.”

“It Ends With Us,” a domestic violence drama based on the bestselling book by Colleen Hoover, was released in theaters this past summer.

At the time, rumors swirled of a feud between Lively and Baldoni, who refused to appear together to promote the flick.

Lively also suffered a barrage of bad publicity, and was dubbed a “mean girl” after a journalist claimed an uncomfortable interview with the star led her to quit her job.

Baldoni’s lawyer, Bryan Freedman, has lashed out at Lively’s new lawsuit, telling TMZ it’s a bid to “fix her negative reputation,” adding the claims are “false, outrageous and intentionally salacious with an intent to publicly hurt.”

He added that she was a “nightmare” on set.

However, according to TMZ, who obtained the legal docs, Lively alleges it was Baldoni who made things untenable while filming the drama.

She alleges “things got so bad during filming, there was an all-hands-on-deck meeting to address what she claims was a hostile work environment.”

Her superstar husband, Ryan Reynolds, attended that meeting.

As part of the tense sit-down, Lively and Reynolds demanded there would be “no more showing nude videos or images of women to Blake, no more mention of Baldoni’s alleged previous ‘pornography addiction,’ and no more discussions about sexual conquests in front of Blake.”

They further stipulated that Baldoni “should not make inquiries about Blake’s weight” and make “no further mention of her dead father.”

Lively also demanded there be “no more adding of sex scenes, oral sex or on camera climaxing” outside the scope of the script she approved when signing onto the project.
