Blake Lively felt ‘fat-shamed’ by Justin Baldoni while filming ‘It Ends With Us’

Blake Lively felt “fat-shamed” by Justin Baldoni when he mentioned her weight while filming “It Ends With Us,” according to a new report.

Baldoni, 40, allegedly asked an on-set trainer how much Lively, 36, weighed before shooting a scene in which he had to lift her, sources told TMZ Wednesday.

The “Jane the Virgin” star has a history of back issues, per the outlet, and wanted to know how to properly train to avoid hurting himself.

Lively, who gave birth to her fourth child just a few months before production began last year, later found out about Baldoni’s comment and felt “bothered” and body-shamed by it, the sources told TMZ.

The report claimed the co-stars also had tension over a kissing scene that the “Gossip Girl” alum thought lasted too long.

Reps for Lively and Baldoni did not immediately respond to to Page Six’s requests for comment.

Insiders previously shared similar sentiments with Page Six, saying Baldoni, who also served as the movie’s director, had fostered an “extremely difficult” work environment for the cast and crew.

“It’s not just Blake,” one source shared. “None of the cast enjoyed working with Justin.”

A second industry insider told us there were a few moments on set that made Lively feel “uncomfortable” about her postpartum body.

People close to Baldoni, however, insisted to Page Six that he would never intentionally make his crew feel unsupported.

Lively and Baldoni first sparked feud rumors when fans noticed the actor had not attended press events with other cast members.

Baldoni also opted out of posing with Lively at the film’s New York City premiere on Aug. 5, which they watched from different theaters.

Sources told Page Six that the actress, who was also a producer, had approved the movie’s final cut and helped bring more of a “feminine” touch to the project based on Colleen Hoover’s 2016 novel.

“As a producer, Blake was given the opportunity to provide edits and feedback to the film,” one insider explained.

In light of the backlash, Baldoni reportedly hired PR crisis manager Melissa Nathan.

Rumors are also swirling that the filmmaker may not return to direct or reprise his role as Ryle in the sequel movie, based on Hoover’s 2022 book “It Starts With Us.”

Though he owns the rights to the novel via his production company, Wayfarer Studios, Baldoni suggested passing the torch to Lively to direct the next adaptation.
