While some co-stars are the beginning of epic Hollywood love stories, not everyone follows that same fate. In fact, some of the most intense drama in Hollywood happens off-screen and these co-star feuds prove it. While many of these stars played on-screen lovers and friends, their relationships when the cameras weren’t rolling were reportedly very different, with many reportedly hating each other in real life.

And while some of these feuds bubbled to the surface, many of these stars kept their tense relationships entirely private during and long after the filming of their movies and TV shows. Given how well these actors did at keeping their feuds off the camera, you might be upset to learn about the secret arguments happening in your favorite shows and movies.

Here are 21 co-stars who reportedly hated each other in real life!

Blake Lively & Justin Baldoni

While the internet can’t get enough of the drama surrounding the cast of It Ends With Us, and how everyone seems to be avoiding the star and director Justin Baldoni, it’s safe to say Baldoni and the movie’s protagonist Blake Lively did not see eye to eye.

According to The Hollywood Reporter, there was a reported “fracture” between them in postproduction. As a result, Lively ordered a new cut from editor Shane Reid, who was an editor on her husband Ryan Reynolds’ movie Deadpool & Wolverine. It’s unclear what cut made it to the theaters, but it’s safe to say tensions have been high ever since.

Florence Pugh & Olivia Wilde

Signs of a feud became apparent when Pugh left Wilde out of her heartfelt thank yous after wrapping Don’t Worry Darling,” a movie in which Wilde both starred and directed. Pugh was later absent from much of the promotion of the film.

Though the exact reasons are unclear, it was reported that Pugh was unhappy with Wilde’s work ethic on set and felt other members of crew were left to pick up her slack.

Wilde also added feul to the fire when she said she was forced to “play mediator” between Pugh and Shia LaBeouf, who was originally cast in the film before Harry Styles was cast in his role.

Reports also alleged Pugh was uncomfortable when Styles and Wilde began a relationship on set.

Tom Hardy & Charlize Theron

Tom Hardy and Charlize Theron allegedly struggled so much with their offscreen beef on the set of 2015’s Mad Max: Fury Road that Theron even asked for a mediator.

The film’s director, George Miller, reflected on the feud during a May 2024 interview with The Telegraph.

“There’s no excuse for it, and I think there’s a tendency in this business to use great performances as an excuse for other disruption that could be avoided,” he said, adding that the actors were “just two very different performers.”

Shannen Doherty & Alyssa Milano

In another long-standing TV feud, Charmed co-stars Shannen Doherty and Alyssa Milano decidedly did not get along. “I think I cried every single night of season 2,” Doherty once told Entertainment Tonight, adding that their competitiveness got the best of them.

Most recently, in an episode of Doherty’s podcast Let’s Be Clear With Shannen Doherty, their third co-star, actress Holly Marie Combs, finally revealed what happened before Doherty left the show. “We were told [by Alyssa] that it’s her or [Shannen], and Alyssa has threatened to sue us for a hostile workplace environment,” Combs revealed on the podcast, per ET. Combs then went on to say that Milano had footage of what made her feel uncomfortable and that she wouldn’t be afraid to use it.

Doherty was then let go of the show while Combs was seemingly coerced to continue despite not wanting to. “They forced me to go back to a show I wanted nothing to do with,” she admitted. “I ended up doing the most hours for the least pay because I just didn’t ask for raises, I didn’t want to be more taken out of the budget, I didn’t want to have no money for guest stars.”

Tim Allen & Casey Wilson

Recently, actress Casey Wilson opened up about her less-than-impressive experience working with Tim Allen in The Santa Clauses.

“Tim Allen was such a b—,” Wilson said in an episode of her B— Sesh podcast, per Variety. “It was the truly single worst experience I’ve ever had with a co-star ever.”

Remembering one moment, Wilson said Allen once finished a scene then went to a producer to talk about Wilson’s acting. “[He] goes over to the producer who is standing four feet from me and goes, and I hear him, he goes, ‘You gotta tell her to stop stepping on my lines,'” she remembered. “The producer turns to me with horror on his face and has to walk one foot to me and he goes, ‘Um, Tim would ask that you stop stepping on his lines.'”

Per Wilson, she said “everybody was walking on egg shells” around the actor on set. “When he was done, he was so f—- rude. Never made eye contact, never said anything. It was so uncomfortable,” she said.

Rachel McAdams & Ryan Gosling

McAdams and Gosling made one of the world’s favorite on-screen and off-screen couples, but the two didn’t always have great chemistry. On the 10th anniversary of the film, director Nick Cassavetes revealed that their relationship was so tumultuous while filming that at one point, Gosling asked to have McAdams removed from the set. The two ended up hashing it out in a room with a producer. It must have worked, because they famously dated in real life from mid-2005 to mid-2007.

Scott Patterson & Lauren Graham

Rumors that these two were feuding stemmed from a 2005 interview in which Graham said her Gilmore Girls character, Lorelai, belonged with her ex, Christopher, and not Patterson’s Luke, a character beloved by fans.

Responding to speculation that she gave this response because of her personal dislike of Patterson, Graham said in another 2005 interview: “No, that’s just what I used to feel.”

When asked how her relationship with Patterson is, Graham said: “It’s fine. I think these characters have a great chemistry and that does mirror our chemistry as people. We’re not intimates.” Taken out of context, fans felt these quotes indicated a poor relationship but the two have seemed cordial over the years.

Jamie Foxx & LL Cool J

Jamie Foxx and LL Cool J’s fighting on the set of 1999’s Any Given Sunday got so out of hand that the Miami-Dade County Police eventually had to get involved. The actors exchanged blows at Miami’s Pro Player Stadium while filming a scene, but both have since said that the feud is behind them.

Tyrese Gibson & James Franco

“I never want to work with him again, and I’m sure he feels the same way. It felt very personal,” Gibson told Playboy of his feud with Franco in 2007 after clashing on the set of Annapolis a year prior. According to reports, Franco’s method acting irked Gibson, particularly when the two were practicing for boxing scenes and the actor refused to do fake punches.

Franco responded to his statements during an interview with Complex magazine, saying, “We’ve made up, or I tried to make up with him. Maybe I was too into that role. I don’t try to be mean to anybody on a movie.”

Lea Michele & Naya Rivera

Rivera didn’t hold back when it came to dishing on her issues with her Glee co-star in her tell-all 2016 book, Sorry Not Sorry: Dreams, Mistakes, and Growing Up. Rivera claimed their “friendship started to break down” because her character began getting “bigger plot lines and more screen time.” Rivera quipped, “I think Rachel — erm, I mean Lea — didn’t like sharing the spotlight.”

Rivera claimed things got so bad that the two were barely speaking by the end of her time on the show. “One of the Glee writers once said that Lea and I were like two sides of the same battery and that about sums us up,” Rivera wrote. “We are both strong-willed and competitive — not just with each other but with everyone — and that’s not a good mixture.”

Will Smith & Janet Hubert

Hubert discussed her longstanding beef with The Fresh Prince of Bel-Air co-star Smith in a 2016 interview, in which she claimed that Smith refused to help her and other co-stars negotiate for a pay raise. The tension resulted in Hubert leaving the show in 1993, after three seasons. The two traded insults in the ensuing years including the year after her departure when Smith went on a radio show to trash Hubert.

“I can say straight up that Janet Hubert wanted the show to be The Aunt Viv of Bel Air Show, because I know she is going to dog me in the press,” the actor said at the time. “She has basically gone from a quarter of a million dollars a year to nothing. She’s mad now but she’s been mad all along. She said once, ‘I’ve been in the business for 10 years and this snotty-nosed punk comes along and gets a show.’”

However, in 2021, Hubert told People that she and Smith had settled their feud and are now friends who keep in touch regularly.

Kim Cattrall & Sarah Jessica Parker

Despite their great on-screen chemistry in Sex and The City, the two would reportedly ignore each other anytime they weren’t filming scenes for the show. The feud is so bad that Cattrall wouldn’t even appear on screen with Parker when she returned for a brief cameo in season two of Sex and the City reboot, And Just Like That…

The feud reportedly stems from Cattrall’s frustration that Parker was paid much higher than other cast members.

Alex Pettyfer & Channing Tatum

Tatum reportedly didn’t like Pettyfer’s attitude on set of Magic Mike, and the bad blood only intensified when Pettyfer didn’t pay rent to a friend of Tatum’s, whose apartment he was renting. Pettyfer confirmed the on-set problems in 2015, saying, “Channing Tatum does not like me — and for many reasons [and] many being my own fault.” He claimed he kept to himself on set because he was “just generally nervous and scared to be myself. I was in character.”

Pettyfer said the apartment he was renting aggravated his allergies and he forgot to pay rent due to his cousin’s death. “All of a sudden,” Pettyfer claims, “I got a very negative email from Channing — rightfully so — saying, ‘Don’t f–k my friends. You owe money. Pay the f–king money. Don’t be a clown.’ And I really took that the wrong way, which I shouldn’t have, and emailed him back and said, ‘I’m in a real negative headspace and can you respect me for a moment and blah, blah, blah.’ And I got hounded through this time of grieving for money.”

“By the end of it,” he continued, “I just said, ‘F–k them, what is money when life is so much more. I’m not paying.’ And I should have just paid. I think he was looking for an excuse to not like me.”

Claire Danes & Leonardo DiCaprio

They played star-crossed lovers, but these two weren’t fond of each other in real life. According to reports, DiCaprio was an avid prankster on the set of Romeo + Juliet and Danes found him immature and childish and actively ignored him. Meanwhile, DiCaprio allegedly found Danes too uptight.

Nina Dobrev & Paul Wesley

The Vampire Diaries co-star and on-screen couple are close friends now but they initially struggled to get along.

“I respected Paul Wesley, I didn’t like Paul Wesley,” she said on a podcast in 2019.

“I remember everyone would walk up to me after the show aired and they’d be like, ‘Are you and Paul dating in real life?’ Everyone thought that we had such good chemistry. I realize now that there’s a fine line between love and hate and we despised each other so much that it read as love but … We really just didn’t get along the first five months of shooting.”

Bill Murray & Lucy Liu

In a 2021 podcast interview, Liu claimed Murray lashed out at her while they were rehearsing a scene together for Charlie’s Angels. Murray was reportedly frustrated with changes made to a scene in his absense from a previous rehearsal. Without specifying what was said, Liu says Murray’s comments were “inexcusable and unacceptable.”

“I stood up for myself, and I don’t regret it,” she said. “Because no matter how low on the totem pole you may be or wherever you came from, there’s no need to condescend or to put other people down.”

Leighton Meester & Blake Lively

They played besties on Gossip Girl but, in 2008, reports claimed the two were far from friends in real life. A source told New York Daily News, “Leighton Meester and Blake Lively avoid each other like the plague while castmates choose sides.”

Though the two denied the feud, Lively’s team did little to quash the rumors when they told Harper’s Bazaar, “Blake and Leighton have never been best friends, and never professed to be. Blake goes to work, does her job, and goes home.”

Selma Blair & Charlie Sheen

The Anger Management co-stars rather fittingly battled their own anger issues behind the scenes of the show and things got so heated that Sheen, an executive producer on the show, even reportedly refused to work with Blair and insisted she be fired, which she was.

According to The Hollywood Reporter, after Blair questioned Sheen’s work ethic, he dismissed her via a strongly-worded text and called her a “c-nt.”

Vin Diesel & Dwayne ‘The Rock’ Johnson

Tensions reportedly arose between the Fast & Furious co-stars when Johnson landed a role in a spin-off of the franchise but Diesel did not.

Johnson let rip on his co-stars in the 2016 Instagram caption that read: “There’s no other franchise that gets my blood boiling more than this one. My female costars are always amazing and I love ’em. My male costars, however, are a different story. Some conduct themselves as stand up men and true professionals, while others don’t.”

Diesel later hit back to say: “I protect everybody including Dwayne. I protected Dwayne more than he’ll ever know.”

Chad Michael Murray & Sophia Bush

These two played love interests on One Tree Hill and even took their love off-screen in a whirlwind romance which saw them get married while filming season two of the show.

However, after just five months the two filed for divorce. Unfortunately, they had to continue starring on the show together for another four years and it was reportedly pretty awkward.

Stana Katic & Nathan Fillion

The feud between these Castle co-star reportedly got so bad that showrunners made Fillion and Katic go to couples counselling together before Katic ended up leaving the show.

“Stana Katic and Nathan Fillion completely despise each other,” a source told Us Weekly. “They will not speak when they are off set, and this has been going on for seasons now.”
