Blake Lively was ‘really impatient’ on ‘It Ends With Us’ set as drama rumors swirl: ‘Tension was so obvious’

With rumors rampant that Blake Lively and her “It Ends With Us” co-star Justin Baldoni had a thermonuclear feud, an on-set spy tells Page Six that the actress was visibly uncomfortable on the shoot.

Last week, the Hollywood Reporter wrote of Lively (who was a producer on the flick) and Baldoni (who was the director) that “there was a fracture among the filmmakers in the postproduction process.”

It seems the alleged divide resulted in two completely different cuts of the movie, one of which was reportedly commissioned by Lively, whose “more feminine edits” made the final cut .

But an experienced insider told us that the weird vibes seemed to have begun before post-production while the flick was still shooting, and that the “Gossip Girl” actress was noticeably antsy on set.

“The tension was so obvious,” we’re told.

“Once she was done with the scene she was really impatient, said, ‘Am I done? Can I go?,’ and as soon as they said ‘Yes,’ there was like a Blake-size hole in the wall.”

They added, “She was so outta there.”

After a source told Page Six Baldoni made Lively feel “uncomfortable” about her postpartum body, TMZ reported that she felt “fat-shamed” after he mentioned her weight while filming.

The actor allegedly asked an on-set trainer how much Lively weighed before shooting a scene in which he had to lift her.

According to the outlet, he has a history of back issues.

And the site reported that there was tension between the co-stars over a kissing scene that the “Sisterhood of the Traveling Pants” star, 36, thought lasted too long.

There’s another strand of angst around the movie’s release because Lively has been accused of being too frothy in interviews about the flick, given that the movie is largely about domestic violence.

Lively’s rep didn’t get back to us.
