Oftentimes, co-stars describe each other as second family. Some of them even end up falling in love. Other times, their relationships are actually quite rocky when the cameras stop rolling. Co-star feuds are some of Hollywood's best-kept secrets, but when actors finally spill about how they really feel when it comes to their actor counterparts on set, that's when things get interesting. From celebs who ran away in fear after kissing their co-star to the ones who ended up leaving the show mid-season to avoid ever speaking again, these co-stars, ahead, reportedly didn't get along behind the scenes. With the amount of drama here, you're going to want some popcorn.
Aniston was reportedly not thrilled when actor Jay Mohr beat out her then-boyfriend Tate Donovan to be her on-screen love interest in the movie, Picture Perfect (1997).
Mohr says instead of taking her anger out on the studio, Aniston took it out on him instead. In an interview with ELLE from 2010, he explained how it was one of the worst filming experiences of his life. “Being on the set of a movie where the leading woman was unhappy with my presence and made it clear from day one.”
He continued, “I hadn’t done that many movies, and even though they screen-tested some pretty famous guys, I somehow snaked into the leading role. The actress said, ‘No way! You’ve got to be kidding me!’ Loudly. Between takes. To other actors on set. I would literally go to my mom’s house and cry.”
On the set of Ridley Scott's 1982 sci-fi classic, Blade Runner, Harrison Ford and Sean Young played lovers in a futuristic Los Angeles. However, when the cameras stopped rolling, the two reportedly couldn't stand each other. It got so bad that the film crew nicknamed their love scene "the hate scene."
When filming the romantic comedy A Countess from Hong Kong, Loren detailed in her memoir, Yesterday, Today, Tomorrow: My Life, an uncomfortable day on set when her co-star groped her.
“All of a sudden, he put his hands on me. I turned in all tranquility and blew in his face, like a cat stroked the wrong way and said, ‘Don’t you ever dare to do that again. Never again!'"
She continued, “As I pulverized him with my eyes, he seemed small, defenseless, almost a victim of his own notoriety. He never did it again, but it was very difficult working with him after that.”
You would think when asked what it was like to kiss your co-star, you would say something nice, but Tony Curtis didn't go that route. The actor said of his Some Like It Hot co-star, Marilyn Monroe, "It was like kissing Hitler."
Before filming the famous movie, the pair had actually dated in real life, but the feelings had changed by the time they started shooting. "She'd gone funny, her mind was all over the place," he said. He then spoke about the scene in which the couple kisses on a yacht (pictured here), saying, "It was awful. She nearly choked me to death by deliberately sticking her tongue down my throat into my windpipe."
The on-screen best friends found it hard to keep up those feelings off screen. In her memoir, Miles to Go, Miley Cyrus shared that she and Emily Osment didn't get along off screen.
"The show felt real to me, and I wanted my relationship with Lilly to feel real too. I knew it didn't have to—show business is show business–but I was disappointed," she wrote. "There were times when I didn't think we could ever be friends. We just couldn't figure out how to get along."
The co-stars ended up working out their feelings and are friends today. They recently had a reunion over Instagram to celebrate 10 years of Hannah Montana.
On the set of Kramer vs. Kramer, Meryl Streep said Dustin Hoffman wasn't easy to work alongside. Some incidents include the time when Streep got approved to make some changes to a scene by writer-director Robert Benton.
When Hoffman saw the changes, he angrily shouted, per The Telegraph, "Meryl, why don't you stop carrying the flag for feminism and just act the scene." Streep commented on the film's scene of spousal abuse to The New York Times and stated how her co-star went overboard.
Then, of course, there was the scene when Hoffman literally slapped his co-star. "This was my first movie, and it was my first take in my first movie, and he just slapped me," she said. "And you see it in the movie. It was overstepping."
Years later, while playing a game of "Marry, Shag, Kill" on Andy Cohen's Watch What Happens Live, Streep chose "to kill" Hoffman without question.
During their first five months of filming, Dobrev revealed on the Directionally Challenged podcast that her and Welsey couldn't stand each other. "I respected Paul Wesley, I didn't like Paul Wesley," she said on the show. But don't worry, the blood-sucking co-stars ended up working things out and are friends today.
"But, of everyone [from the Vampire Diaries cast], I think I probably see him the most and hang out with him the most…We are probably the closest," she said on the podcast. "We hang out a lot. We're really good friends. And I love his wife. It's so funny how time changes everything because I never thought that he would be one of my best friends."
On Andy Cohen's Watch What Happens Live, Collins shared the soap opera co-stars didn't talk for an entire season.
"[At] the People's Choice Awards, we won as a whole company, and we were told that when we were being presented with the award, it was going to be given to John," she said on the late-night talk show. "However, they gave it to me. He didn't like that. I said, 'Oh, thank you very much, I'm going to give it to our fearless leader,' and he said, 'She's said enough,' and that was it. And it was very unpleasant, I have to say. It wasn't nice."
The famous musical, Singin' in the Rain, captured hearts, but it wasn't exactly a joy to make for some of its actors. In Reynolds' memoir, Unsinkable, she recalled her time on set with Kelly, writing, "He came to rehearsals and criticized everything I did and never gave me a word of encouragement."
She also detailed what it was like when their characters kissed. In her memoir she said, "Gene took me tightly in his arms...and shoved his tongue down my throat. 'Eeew! What was that?' I screeched, breaking free of his grasp and spitting. I ran around frantic, yelling for some Coca-Cola to cleanse my mouth. It was the early 1950s, and I was an innocent kid who had never been French-kissed. It felt like an assault. I was stunned that this 39-year-old man would do this to me."
According to The Hollywood Reporter, Blair voiced her concerns about Sheen's work ethic while filming two episodes a week that often found him with more than 40 pages of dialogue per script. Sheen then fired Blair by sending her a nasty text in which he called her a "c**t" and threatened to leave the show if she returned to set. She left the show.
In 2017, during a segment on Watch What Happens Live, he was asked to rank some previous co-stars from favorite to least favorite to work with. He commented on his former co-star Blair and his former Two and a Half Men costar Jenny McCarthy saying, "I'd like to mash those two together and then kick them to the curb. They deserve each other."
Despite having ample opportunity (and good plot reasons) to have met in Westeros, Flynn and Headey's Game of Thrones characters, Bronn and Cersei, have conspicuously never shared the screen. Why? Sources have said that the former real-life couple aren't on speaking terms and refuse to work together.
"Jerome and Lena aren't on speaking terms anymore and they are never in the same room at the same time," a source told The Telegraph in 2014. "It's a pity because they appeared to have patched things up for a while, but now the word is they should be kept apart at all costs."
Though rumors that the actors outright hated each other behind the scenes don't seem to be true (thankfully), Luke and Lorelai's on-screen chemistry didn't translate to an awesome relationship off camera.
"It's fine," Graham explained to TV Guide when asked about her relationship with Patterson. "I think these characters have great chemistry and that does mirror our chemistry as people. We're not intimates."
When the reporter asked if they were "best friends," she gave a quick and definitive "no" as her answer.
The vibe between Roberts and Nolte was so bad that their on-screen romance in I Love Trouble was a hard sell—the chemistry just wasn't there. A 1994 story in the Los Angeles Times explored the friction between the actors on set.
"Roberts reportedly wasn't thrilled with Nolte's machismo, so she would deride and insult her co-star," said the publication. "Some on the set claim that he became so annoyed with her attitude that he would do things to agitate her even more. The discord was so intense, the sources say, the two played more to stand-ins than to each other."
Crawford and Davis' feud on the set of What Ever Happened to Baby Jane? was so infamous that it was the subject of the first season of Ryan Murphy's anthology series, Feud. The drama between the Hollywood legends was said to have started when Crawford married Franchot Tone, who just happened to be the love of Davis' life. "I have never forgiven her for that, and never will," Davis once said of Crawford in an interview years later.
Rumors swirled that the two Sex and the City actresses weren't great friends in real life, with claims that Cattrall had become upset when she learned that Parker earned more than her co-stars. In November 2009, Parker publicly denied the feud telling ELLE, "I don't think anybody wants to believe that I love Kim. I adore her. I wouldn't have done the movie without her."
Years later, talks of a third SATC movie in the works were shut down when rumors about Catrall being a diva started circulating; Hollywood gossip insinuated that the film wouldn't happen because she was holding up negotiations with her demands. Catrall took personal offense to the rumors and fired back by throwing some shade SJP's way.
"This is really where I take to task the people from Sex and the City and specifically Sarah Jessica Parker in that I think she could have been nicer. I really think she could have been nicer. I don’t know what her issue is, I never have.”
The actresses starred together on the '90s hit Beverly Hills: 90210, but Doherty left the show after season four reportedly due to problems getting along with her cast mates. In a 2014 interview with E! Online, Garth opened up about her own feud with Doherty.
"We were locked in this sound stage for 14–16 hours every day. There were times when we loved each other and there were times when we wanted to claw each other's eyes out," she explained.
Doherty faced co-star drama again on the set of her WB series, Charmed. After several reports of behind-the-scenes drama with Alyssa Milano, Doherty left the series after the third season.
"There was too much drama on the set and not enough passion for the work," Doherty explained in an interview with Entertainment Tonight about her departure from the series. "I'm 30 years old and I don't have time for drama in my life anymore."
The co-stars have since made amends. In 2017, Milano told E! that they were in regular contact. "Shannen and I talk a lot on Twitter via [direct messenger] and I spoke to her maybe two or three days ago," she said. "She was on vacation and we decided that we're going to get together. That date has not been set yet."
In her memoir, Sorry Not Sorry: Dreams, Mistakes and Growing Up, the late Naya Rivera addressed her long-rumored feud with Glee co-star Lea Michele.
"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."
One of the best parts of the TLC makeover show What Not to Wear was the natural chemistry between fashion gurus Stacy London and Clinton Kelly, but as it turns out, their friendship wasn't as rocksteady as it appeared. When Kelly released his memoir I Hate Everyone, Except You in 2017, he hinted that there was some serious tension between the co-stars.
London didn't take kindly to the book and ended up blocking Kelly on social media. "I can’t stop people from the way they behave. I can’t stop them from being angry with me, hurtful to me, or indifferent to me," the fashionista later wrote on Instagram. "I can block ex-friends and ex-lovers, people I feel wronged by, but to what end? For the most part, these people aren’t even looking at my accounts in the first place and even if they were, why would being able to see this highlight reel of my life matter in the slightest?”
The pop superstars infamously butted heads when they served as judges together on American Idol.
"Mariah has been saying little things to jab at Nicki from day one of shooting," a source told People of the feud. "Mariah doesn't think Nicki can sing and doesn't think she should be judging folks. Nicki has been taking all of the jabs, but on this particular day she lost it."
We first met Tisdale and Grabeel in the 2006 Disney musical phenomenon High School Musical, where they starred as fame-hungry twins Sharpay and Ryan Evans. While the two may have seemed as thick as thieves, the actors weren't actually friends while they were filming the HSM franchise.
Tisdale spilled the tea on their relationship when they reunited in 2017 on her YouTube channel. "We were not close. We were not good friends—let's be honest. It's been 10 years, so we can talk about it." she laughingly admitted. "We hated each other. Like, I'm not kidding."
"We didn't get off on the best foot," Grabeel chimed in.
In the case of One Tree Hill co-stars Chad Michael Murray and Sophia Bush, love came first and then came the on-set awkwardness. The co-stars married in April 2005 and separated just a few months later in September 2005. They both continued as series regulars through 2009. Awkward.
Of all of the guest appearances on ABC's smash sitcom Ugly Betty, Lohan's run on the show might have been the most tumultuous. The actresses reportedly didn't get along, with a source saying that "America couldn't handle Lindsay stealing her thunder." There were even rumors that Ferrera lobbied to have Lohan's arc cut short.
Fans shippped Mulder and Scully for years, but the stars didn't always get along in real life. "Familiarity breeds contempt," Dochovny once explained. "We used to argue about nothing. We couldn't stand the sight of each other."
Heigl hasn't headlined many major films or television shows since her departure from Grey's Anatomy, and many suspect that it's due to a falling out with Grey's creator Shonda Rhimes. When Heigl earned an Emmy nomination for her role as Izzy Stevens in 2008, the actress actually opted out because she wasn't given enough quality material to even be considered for an Emmy. "I did not want to potentially take away an opportunity from an actress who was given such materials." Heigl explained in a statement that year.
Rhimes kept it professional, but the damage was already done. Even when Heigl publicly expressed a desire to revisit her role on the show, the showrunner coolly declined. "There are no Heigls in this situation," Rhimes said of the Scandal cast in a 2014 The Hollywood Reporter interview. "I don't put up with bullshit or nasty people. I don't have time for it."
Heigl wasn't the only Grey's star involved in beef. Many of her castmates were also dealing with their own in-house feuds. Most famously, Isaiah Washington was fired from the ABC medical drama after it was revealed that he used a homophobic slur towards T.R. Knight during an intense argument with Patrick Dempsey. Washington issued several public apologies following the incident, but was only able to return to the show for a guest appearance years later, much to the ire of some of the cast and fans.
In 2015, creator Shonda Rhimes confessed to killing off characters on her show because she didn't like them, and fans immediately began speculating that she was referring to Dempsey. Known for being somewhat of a diva, it's likely that his character Derek Shepherd was written off the show because he didn't get along well with the showrunner.
Sorry, Gossip Girl fans—your favorite Upper East Siders aren't really as close as you thought they were. Lively and Meester reportedly had a strained relationship behind the scenes, which sources attributed to long working days on set. One Gossip Girl source spelled out the actresses' issues with each other plainly: "Leighton thinks Blake is an egomaniac who views her time on the TV set as slumming. And Blake feels stifled. She’s just ignoring her co-star because she knows bigger things are in store."
In response to the drama, Lively's publicist didn't even really try to spin the rumors. "Blake and Leighton have never been best friends, and never professed to be,” the statement clarified. "Blake goes to work, does her job, and goes home."
