It Ends With Us fans are convinced there's a huge feud between Blake Lively and Justin Baldoni - here's why

Fans anticipating the release of  'It Ends With Us' are convinced costars Blake Lively and Justin Baldoni are embroiled in a fierce feud - after noticing some suspicious behavior between the two cast members.

The highly-anticipated movie, based off Colleen Hoover's novel of the same name, is set to hit theaters on Friday, August 9.

But some fans believe Blake, 36, has beef with Justin, 40 - who on top of acting in the film, also directed it - after claiming they spotted some tension between the stars at the New York City premiere earlier this week.

Blake and Justin didn't pose for any pictures together at the event, despite playing the two main characters and love interests in the flick.

She happily took photos with her other costars like Jenny Slate and Brandon Sklenar, but not Justin.

Social media users are convinced that It Ends With Us costars Blake Lively and Justin Baldoni have become embroiled in a fierce feud

Two days later, Blake attended a photo call in London for the film with some of the other stars - but Justin was mysteriously absent.

In addition, the two haven't done any press together in the weeks leading up to the film's release.

Instead, Blake sat down for an interview with her costar, Brandon, last month; she and Brandon also participated in a promotional video with It Ends With Us stars Alex Neustaedter and Isabela Ferrer, but Justin had no part in it.

Eagle-eyed social media users also noticed that both Blake and author Colleen unfollowed Justin on Instagram recently.

Between their lack of interactions and the social media move, many people on the web are wondering if there was drama between Blake and Justin on set.

And X, formerly Twitter, has been flooded with posts about the rumored divide. 

'Kind of NEED to know what went on with Blake Lively and Justin Baldoni on that It Ends With Us set because this press tour is crickets,' one person wrote.

'I know one of you out there has that info so share it with the class.'

'Someone please find out the tea on the Justin [and] Blake from It Ends With Us chaos and report to me because I'm snoopy,' begged another user.

Someone else agreed, 'My nosey a** needs to know why Justin Baldoni and Blake Lively aren't promoting It Ends With Us together?

'Like, isn't he the actual director of the film and a main character?'

'Justin Baldoni, Blake Lively, and Brandon Sklenar are all at the premiere of It Ends with Us in NYC and they're all still not interacting with Justin,' a fourth tweet read. 

'Mind you, he's the producer, director, and a main character. Oh best believe I'm going to get to the bottom of this tea.'

A fifth said, 'Blake Lively and Justin Baldoni are avoiding each other like the plague. 

'You would almost forget that Justin directed the movie and is her costar. What happened on the It Ends With Us set?'

'Is it me or is Justin Baldoni being ousted by the rest of the cast and crew?' a different person added.

'They're doing separate promos, no pictures together, they don't even mention each other.

'Something definitely happened behind the scenes between him and Blake and I need to know what.'

To make matters more suspicious, actress Jenny completely dodged a question about Justin on the red carpet at the premiere on Tuesday evening.

'What was it like having [Justin] be director but also a scene partner?' a Deadline reporter asked the star.

'I mean what an intense job to have to do so many things. I found myself being like, "Wow, I just want to have one job at once,"' she replied.

'I've often felt that way, I really like writing and it's special to be able to be a writer but I was looking around like, "Yeah I'm good with just acting." I love it.'

Justin sat down on the Today show this morning for an interview, and he appeared to brush off the feud rumors by gushing over Blake on air 

'I don't know if you know how smart and creative she really is,' he said. 'She's best known as an actress and of course she's a fashion icon, but she's so much more than that'

Justin sat down on the Today show this morning for an interview, and he appeared to brush off the feud rumors by gushing over Blake on air.

When asked about what it was like to work with the Gossip Girl alum, he had nothing but positive things to say.

'I don't know if you know how smart and creative she really is,' he said. 

'She's best known as an actress and of course she's a fashion icon, but she's so much more than that. 

'She is a dynamic creative - she had her hands in every part of this production and everything she touched, she made better.'

The movie follows Lily Bloom (played by Blake), a floral designer who falls in love with neurosurgeon Ryle Kincaid (portrayed by Justin), years after losing touch with her first love, Atlas (played by Brandon), after he joined the military. 

But things get dramatic after Lily reconnects with Atlas after running into him at a restaurant, just as her romance with Ryle starts to turn toxic.

DailyMail.com has contacted representatives for Justin, Blake and the movie's production company Wayfarer Studios. 

This isn't the first time that rumors of a feud between costars plagued a film's release. 

Back in 2022, Olivia Wilde's psychological thriller Don't Worry Darling was marred in scandal. 

For those who forgot - which is unlikely, due to how much it was talked about at the time - director Olivia and main star Harry Styles struck up a spicy romance in the middle of production, which didn't go over well with her ex, Jason Sudeikis.

In addition, there was speculation of a fight between Olivia and actress Florence Pugh on set, and Harry was rumored to have spit on costar Chris Pine at the Venice Film Festival.
