Director of It Ends With Us 'fought with Blake Lively' over final cut of film and they now 'hate each other'

Sources with knowledge about the making of Blake Lively's new movie It Ends With Us have claimed the star fought with the director over the final cut.

Lively stars alongside Justin Baldoni, Jenny Slate, Hasan Minhaj and more in the romance-drama movie, which arrives in theaters today (August 9) after being adapted from author Colleen Hoover's bestselling book.

Baldoni also directed the movie, but despite working side-by-side for so long Lively and Baldoni noticeably did not appear to pose together for any photos at the New York City premiere for the movie this week.

Internet sleuths quickly began to question the atmosphere at the event and the accompanying press tour, with one person going as far as to suggest the pair were 'avoiding each other like the plague'.

Committed social media users also spotted that both Blake and Hoover had apparently unfollowed Baldoni on Instagram.

Now, sources cited by TheInSneider - aka Jeffrey Sneider, 'Hollywood's most fearless journalist' - have claimed tensions between Lively and Baldoni came about due to a difference of opinion.

The insiders have claimed there were different cuts of the film competing against each other in the editing stage, with Baldoni and Lively on opposing sides.

Apparently Baldoni's version scored higher with audiences, but Lively allegedly took action to make sure her cut 'won'.

The sources claimed that Lively enlisted her husband, Ryan Reynolds, for help, and that he 'basically took over the movie and buddied up to author Colleen Hoover to see that their cut won'.

As a result, 'Baldoni and Blake hate each other', the sources have alleged.

One claimed: “It’s wild that the cast would shun Justin and not do press with him. It makes no sense because he’s the only one acting professional."

Reynolds smiled alongside Lively at the premier in New York, and in an interview with People, the star revealed her husband had contributed to the movie in at least one capacity.

She said: "The iconic rooftop scene, my husband actually wrote it. Nobody knows that but you now."

Lively continued: "We help each other. He works on everything I do; I work on everything he does. So his wins, his celebrations are mine and mine are his."

In spite of the rumors surrounding the movie, Baldoni has spoken highly of Lively and described her as a 'creative force'.

Speaking to People, he said: "She's an executive producer on the film, and she is so brilliant."

UNILAD has contacted representatives for Lively and Baldoni for comment.
