Blake Lively sues It Ends With Us costar Justin Baldoni for sexual harassment as shocking claims are...

Blake Lively is taking legal action against her ex-co-star and director of 'It Ends With Us', Justin Baldoni, citing claims of sexual harassment.

The star from Gossip Girl alleges that Baldoni created a harmful work environment. She claims that he shared explicit videos and photos of other women with her, along with discussions about his supposed past addiction to pornography, according to TMZ.

Baldoni's team has denied the accusations and asserts that the lawsuit is an effort to restore Lively's reputation, which took a hit following the troubled movie's launch.

The two actors played leading roles together in the eagerly awaited film based on the well-known Colleen Hoover novel of the same title that was released earlier this year.

Nonetheless, the debut was overshadowed by various controversies after fans noticed friction between Lively, 37, and Baldoni, 40.

Lively has alleged that Baldoni asked her inappropriate questions regarding her weight, made remarks about her deceased father, and made sexual comments about the cast and crew.

The circumstances became so difficult that she and her husband, Ryan Reynolds, requested urgent discussions while filming to address and halt the behavior, as stated in the lawsuit.

Lively also asked that no additional sex scenes, oral sex, or on-screen climaxes involving her be included beyond what she agreed to in the original script when she joined the project, according to the legal documents.

Blake Lively is taking legal action against Justin Baldoni, her co-star and director from 'It Ends With Us', claiming he sexually harassed her.

The Gossip Girl actress alleges that Baldoni created a harmful work atmosphere while they were shooting.

The lawsuit claims that the studio supposedly agreed to the demands, but the film's release faced delays due to a conflict between Lively and Baldoni regarding its marketing strategy.

Keen observers quickly noticed the chilly dynamics between the film stars, leading to reports about the divide starting to circulate.

Lively asserts that Baldoni's team initiated a campaign of 'social manipulation' aimed at damaging her reputation.

The legal complaint contains messages from the director's publicist to the studio that reportedly state Baldoni "wants to make it seem as if [Lively] could be taken down" and "we can't say we will ruin her."

Baldoni's attorney, Bryan Freedman, responded to the lawsuit, calling it "untrue, scandalous, and deliberately provocative, aimed at causing public damage."

He argued that the lawsuit is Lively's way of trying to repair her tarnished image following allegations of difficult behavior on set.

Freedman stated that this involved "threatening to skip the filming, refusing to promote the movie, which ultimately contributed to its failure at the box office."

Since its release in August, It Ends With Us has become one of the year's most discussed films, but not for the right reasons.

Earlier this year, the pair played lead roles together in the eagerly awaited film adaptation of the well-loved Coleen Hoover novel of the same title.

However, Lively asserts that Baldoni made her feel uneasy by sharing nude videos and pictures of other women, as well as talking about his supposed past addiction to pornography.

The romantic drama centers on Lily Bloom, portrayed by Blake Lively, as she finds herself caught in an abusive relationship with Ryle Kincaid, played by Justin Baldoni.

One reported disagreement seemed to revolve around the movie's marketing approach. Lively reportedly wanted to present the story in a more positive light, while Baldoni believed it should emphasize the theme of abuse more strongly.

Sources have disclosed troubling details regarding the tension on set, stating to DailyMail.com that Blake and Justin had conflicts due to his 'dismissive' response to her 'contributions' during the filming of scenes that depicted abuse.

An insider reported that Justin concentrated solely on what he saw as the perspective of an abusive man and had a rather 'male-centric' attitude toward the issue.

As speculation about the dispute continued, reactions on social media started to sway away from Blake. She faced criticism for how she addressed the situation during interviews meant to promote the film.

She faced backlash for being 'out of touch' and 'superficial' after interviewing her It Ends With Us co-stars without addressing the important themes of the film.

Another disagreement arose when Baldoni inquired about Lively's weight before a scene in which he needed to lift her.

The famous actress allegedly expressed that this made her feel 'body-shamed,' while people close to Baldoni argued that he was simply trying to take care of his back after an injury.

Fans noticed the strained relationship between the main actors while promoting the film.

In her lawsuit, Lively asserts that Baldoni displayed explicit photos and videos of women, discussed a supposed past addiction to pornography, and made inappropriate sexual remarks about the cast and crew.

Rumors of tension behind the scenes began circulating on BookTok, as social media users pointed out that Lively and Baldoni have never been seen posing together on red carpets.

Fans have noticed that Lively, author Hoover, and the rest of the cast do not follow Baldoni on social media, while he follows each of them.

In early August, The Hollywood Reporter verified that there was indeed a conflict between Lively, who took on the role of producer for the movie, and Baldoni.

Lively also leveraged her influence as a producer to request a brand-new version of the film from editor Shane Reid, who previously worked on her husband Ryan Reynolds' successful movies, Deadpool and Wolverine.

It's unclear if any material from Reid's version made it into the film, which is credited to editors Oona Flaherty and Robb Sullivan.

Unlike many projects where controversy influences box office performance, "It Ends With Us" managed to be a commercial success, even though critics had mixed opinions about it, giving it a score of only 57 percent on Rotten Tomatoes.
