Relive the most EXPLOSIVE on-set feuds as Blake Lively and Justin Baldoni's legal battle continues

While on screen, they may look like they're as close as could be, some costars from your favorite shows and movies actually secretly hated each other in real life. That's right, many beloved series and films were filled with explosive drama, bitter on-set feuds, intense rivalries, and nasty fall-outs behind the scenes, all unbeknownst to its viewers. Other times, the stars couldn't hide their disdain for one another and the tension trickled into the press tours or premieres, making it obvious to the world that something went down on set.

Take Blake Lively and Justin Baldoni for example. The It Ends With Us stars' showdown has completely captivated the globe and has even now erupted into a massive legal battle involving multiple lawsuits and a slew of shocking claims, including accusations of sexual harassment. The entire world has watched on as the two actors have continuously battled it out publicly in recent months, with their legal teams hurling insult after insult at one another.

Their messy drama seemed to overshadow the release of the movie, and it's certainly not the first time a set of actors have come to blows after starring in something together. In fact, some feuds in the past have become so intense that they have led to the stars cursing each other out, storming off of the set, or even on rare occasion physically attacking each other. Amidst the ongoing It Ends With Us saga, FEMAIL has revealed all the other costars who have butted heads while filming a movie or show.

From Sex and the City's Sarah Jessica Parker and Kim Cattrall to Don't Worry Darling stars Olivia Wilde and Florence Pugh, take a look into most explosive on-set feuds of all time. Rumors first erupted that Blake Lively and Justin Baldoni (seen in the film) were feuding when they failed to do any promo together during the press tour and didn't interact at the premiere. Things took a shocking turn in December when Blake filed an explosive lawsuit against Justin, in which she alleged he sexually harassed her and created a hostile work environment on set.

Blake and Justin began filming the movie adaptation of the beloved Colleen Hoover novel in May 2023, and it wrapped in early 2024. On the outside, everything seemed to go well, but when the two stars headed off on a press tour ahead of its release in August 2024, fans began to suspect that something was amiss. They were quick to notice that Blake and Justin failed to do any promo together, despite playing the two main leads and lovers in the flick.

They didn't even interact once or pose together on the red carpet at the premiere, resulting in a barrage of rumors that they were feuding. Things took a shocking turn in December when Blake filed an explosive lawsuit against Justin with the California Civil Rights Department, in which she alleged he sexually harassed her and created a hostile work environment on set. Following Blake's lawsuit, the New York Times released an article about the ordeal and called it a 'Hollywood Smear Machine,' claiming Justin and his PR team 'pushed to prevent stories about Justin's behavior' and 'reinforced negative ones' about Blake.

Justin denied her claims and responded by filing his own $400 million lawsuit against the actress. It was filled with his own fair share of shocking claims - including one that Blake enlisted her husband, Ryan Reynolds, and her pal Taylor Swift to 'pressure' him into allowing her to make changes to the script. Since then, the two stars' lawyers have continuously hurled insults at one another. The New York Times then released an article about the ordeal and called it a 'Hollywood Smear Machine,' claiming Justin and his PR team 'reinforced negative' stories about Blake.

Justin denied her claims and responded by filing his own $400 million lawsuit against the actress. Last month, Blake and her husband Ryan's legal team requested a gag order to curb what they called 'improper conduct' by Justin's attorneys, citing an alleged 'harassing and retaliatory media campaign' against the couple. It came after Justin's attorney released shocking behind-the-scenes footage from the set of It Ends With Us.

The explosive video, exclusively released by DailyMail.com, showed all three takes of a dance scene between the costars - revealing the pair were on apparent great terms before the actress accused him of sexual harassment. Blake hit back at the clip's release, with her lawyers saying it actually proved that she was uncomfortable during the scene. Her team said that sharing the video with the media 'was another example of an unethical attempt to manipulate the public' and 'a continuation of their harassment and retaliatory campaign.'.
