Love and Betrayal: A-List Actors Accused of Cheating with Their Co-Stars

Darren March 22, 2024

It’s no secret that most A-list movie stars are usually very attractive people. It shouldn’t be surprising that they mostly date and marry each other. One of the aspects that we love most about great films is when the lead actors have strong chemistry. But sometimes it’s so strong that they face accusations of cheating with their co-stars.

Let’s look at some of the most dramatic and interesting stories about actors allegedly cheating on their partners. Some of these big names admitted that they crossed the lines of their relationship boundaries. Others deny that anything untoward happened but where there’s smoke there’s usually a fire.

Johnny Depp and Amber Heard

Let’s start with a clear-cut case of cheating. Depp and Heard are one of the most infamous Hollywood couples ever because of the way their nasty court case. They aired their dirty laundry in public in a shameless legal battle that damaged both of their reputations.

Maybe this was karma for the way they met because Depp cheated on his wife of 13 years. Depp and Heard met on set in 2011’s The Rum Diaries. Heard had no problem being a home wrecker while Depp abandoned his two children and wife Winona Ryder (via People).

Lady Gaga and Bradley Cooper

Look at the photo below and try to convince anybody that Lady Gaga and Cooper don’t love each other. The pair starred together in A Star Is Born to rave reviews. They had incredible on-set chemistry and showed their close connection in subsequent interviews (via Vogue).

They raised eyebrows with a sensual performance of ‘Shallow’ at the 2019 Oscars. Cooper is in a committed relationship with Irina Shayk but that didn’t stop people from accusing him of cheating. Viewers could cut the romantic tension between Cooper and Gaga with a knife.

Kristen Stewart and Robert Pattinson

It’s easy to forget the Twilight franchise’s massive cultural impact. The teen vampire movies transformed Stewart and Pattinson into superstars as legions of fans adored their on-screen love story. Then they delighted everybody when they started dating in real life.

However, Stewart rocked the world by cheating on her co-star. The teenage star had a shocking affair with her Snow White And The Huntsman director Rupert Sanders. Pattinson forgave Stewart and they gave it another go but in the end, they were young and broke up again (via Outlook India).

Ariana Grande and Ethan Slater

Grande is one of the biggest pop stars on the planet. However, rumors suggest that her ex-husband won’t want to hear her voice again. That’s because of an alleged cheating scandal that saw Grande reportedly date a co-star. She publicly linked up with her fellow Wicked actor Ethan Slater in the month after the divorce.

This raised eyebrows for several reasons. Firstly, there was the story that she had an affair with Slater during filming. Then there was the outrageous fact that Slater’s wife Lilly Jay recently had their first child. People accused him of being a garbage human and labeled Grande a ‘home wrecker’ (via Perez Hilton).

Russell Crowe and Meg Ryan

Crowe and Ryan are two of the most beloved actors of their generation. However, the pair shocked fans when they had an affair when they filmed Proof Of Life. Ryan admits that it was wrong because she married Dennis Quaid. However, the ’90s icon said that infidelity didn’t end her dysfunctional marriage.

“My marriage dissolved before it became a sport for the press,” she told the media in 2000. “The public and the press tuned in way after.” Furthermore, it became clear that Quaid also cheated on Ryan multiple times throughout their time together (via Best Life Online).

Olivia Wilde and Harry Styles

Everybody knows that Styles and Wilde had a relationship. However, they may not know the alleged seedy circumstances that saw them get together. The duo worked together on Don’t Worry, Darling after Styles replaced Shia LaBeouf. Meanwhile, Wilde was at the end of a nine-year marriage to Jason Sudeikis.


Multiple sources reported that Wilde and Styles had an affair behind the scenes. They claim this left Sudeikis heartbroken and prompted him to publicly serve her for custody of their children. There’s plenty of cheating in Hollywood and it rarely ends well (via Harper’s Bazaar).

Ben Affleck and Blake Lively

Affleck features a couple of times on this list and has a reputation for being a lady’s man. His relationship with Jennifer Garner came to an acrimonious end. Unfortunately, for Lively, she found herself in the middle of rumors about Affleck’s alleged infidelity (via Cafe Mom).

Lively was Affleck’s co-star in his movie The Town and the photo above promoted cheating speculation. It’s a bit of a stretch because they’re just hanging out but this was a major story in 2010. For her part, Lively broke up with Penn Badgley that year and started dating her future husband Ryan Reynolds.

Emma Stone and Andrew Garfield

Rumors suggest that Garfield cheated on Shannon Woodward because he wanted to be with Stone. The actor met the future two-time Oscar winner on the set of The Amazing Spider-man. Their on-screen chemistry evolved into real love and the couple began a genuine romantic relationship.

However, the timeline suggests that Garfield didn’t do things the right way. Nobody wants to face accusations of cheating but that’s what he experienced. In the end, their relationship didn’t go anywhere but now they have families with other people (via Koimoi).

Harrison Ford and Carrie Fisher

Han Solo and Princess Leia have one of the most celebrated fictional romances ever. However, their Star Wars actors also had a brief tryst. Fisher was only 19 when she began the secret relationship with her co-star. Ford was 13 years older than her and surprised her because she was very insecure.

Fisher wrote in her biography: “We all became famous at that time, but there were other things to focus on, and certainly the affair was a formidable distraction. And maybe that made the fame less confusing because it didn’t have all of my focus (via The Guardian).”

Morena Baccarin and Ben McKenzie

Brazilian star Baccarin has enjoyed success on the big and small screens in the likes of Deadpool and Gotham. However, she was also at the center of one of Hollywood’s wildest cheating scandals. Baccarin married her film director husband Austin Chick and all appeared to be right in the world.

Then she met McKenzie on the set of Gotham and began a passionate affair. The craziest aspect of this was that she was three months pregnant with his child before she told Chick. Unsurprisingly, he filed for divorce and the couple separated. Then Baccarin married the father of her newborn son (via Us Magazine).

Will Smith and Margot Robbie

Who knows what went on behind the scenes in Will and Jada Pinkett Smith’s marriage? Everything came to a rapid conclusion after he worked with Robbie. A picture went around the Internet of the shirtless superstar and Robbie in lingerie. Reportedly, this infuriated Smith’s wife, and cheating rumors emerged.

The pair worked together in multiple movies including Suicide Squad and Focus. However, Robbie denies that anything happened between them. She even got on Twitter as she tried to shut down rumors but where there’s smoke there’s a fire (via Clutchpoints).

Kenneth Branagh and Helena Bonham Carter

Branagh and Bonham Carter are two of the UK’s greatest actors. The pair met in 1994 when they worked together on Frankenstein. Passion kindled between them and they began a five-year affair. Unfortunately, Branagh also broke his wife’s heart in the process (via InStyle).

Oscar-winner Emma Thompson discovered that Branagh was cheating on her and filed for divorce. She openly admits that the divorce devastated her and that it left her in a depressed state. Fortunately, she met her true love Greg Wise in 1995 and the couple have been together for almost 30 years.

Dominic West and Lily James

Nobody knows how West pulled his marriage back from the brink after cheating with James. The veteran actor was almost 20 years older than his co-star. They worked together on The Pursuit of Love and sparks flew between them. Paparazzi caught them kissing at a cafe in Rome.

But West married Catherine FitzGerald and had four children with her. The pair even faced the media as they announced they would continue working on their marriage. West has a history of womanizing so maybe they have secret rules behind the scenes (via Grazia Daily).

Justin Timberlake and Alisha Wainwright

Timberlake and Wainwright defended cheating rumors after the image below went viral in 2019. The pair tenderly held hands at a cafe in New Orleans. Wainwright put her hand on his knee several times as she threw gas on the fire. But they denied that anything untoward was happening.

Meanwhile, Timberlake says that Jessica Biel is the woman of his dreams and that he can’t go back. Maybe this was innocent but he knows that cameras are always watching him. It’s not easy to demonstrate innocent affection because the paparazzi always want to turn it into something more (via People).

Jessica Simpson and Johnny Knoxville

Most people know Knoxville as the face of the Jackass franchise. However, he was also a genuine actor and worked with Simpson on The Dukes of Hazzard movie. She openly admits to cheating on her husband Nick Lachey with her co-star. But she has no regrets because Knoxville provided solace in a difficult time (via Harper’s Bazaar).

In her book, Simpson described how she felt when she was with Knoxville. She wrote: “I could share my deepest authentic thoughts with him, and he didn’t roll his eyes at me. He actually liked that I was smart and embraced my vulnerabilities. He believed in me and made me feel I could do anything.”

Angelina Jolie and Billy Bob Thornton

It’s wild but Jolie doesn’t mind being the other woman as she’s proven on several occasions. Before the Brad Pitt chaos, there was her cheating scandal with Thornton. She was single when she encountered the engaged star on the set of Pushing Tin. Jolie was a home wrecker as the pair had a short and passionate affair.

Laura Dern broke off her engagement to Thornton after she discovered that he was cheating on her. She couldn’t believe that he humiliated her so badly. Often, we forget that celebrities are real people who feel human emotions. They also live these moments in the public eye (via ABC News).

Kate Hudson and Owen Wilson

Cheating often triggers the end of relationships. That’s what happened after Hudson had a secret six-month tryst with her You, Me, And Dupree co-star, Wilson. The pair vibed well and dated behind the scenes but there was one big problem. Hudson was in a six-year marriage to Chris Robinson.

Robinson discovered that his wife was cheating on him and justifiably filed for divorce. Hudson and Wilson engaged in a dramatic on-off relationship that saw marriage proposals and suicide attempts. Ultimately, they gave up because things were too unhealthily intense between them (via OK!).

Tom Cruise and Nicole Kidman

Kidman openly admits that she was too young when she married Cruise. She met the charismatic action star on the set of Days of Thunder and they began a passionate affair. The problem was that Cruise was cheating on his then-wife Mimi Rodgers. However, he didn’t care because Kidman had his full attention.

Cruise has a long history of unhappy relationships. After finalizing his divorce from Rodgers, he married Kidman in a well-publicized ceremony. But they divorced in 2001 after she realized that it wasn’t working. Marriage changes the dynamic between every couple and sometimes it breaks them (via Good Morning America).

Jennifer Lawrence and Liam Hemsworth

Many people think that Hemsworth cheated on Miley Cyrus when he was working with Lawrence. The pair were co-stars in The Hunger Games and became genuine superstars. This also sparked rumors that they had a secret fling behind the scenes (via Business Insider).

Lawrence responded to the story in an interview. She said: “It’s not true. Total rumor. I mean we all know we only kissed one time and it was years after they broke up.” The reality is that only the involved parties will ever be able to say what happened. Nonetheless, the cheating rumors didn’t fade away.

Lily James and Armie Hammer

James is one of several actors who appears several times on this list. She allegedly had dalliances with several married men including Hammer. Tabloids reported that he had an affair with James when they worked together on Rebecca. Then in 2020, he split from his wife Elizabeth Chambers.

Reportedly, the now-disgraced star had James in his contacts as ‘Adeline.’ This was allegedly James’ name on call sheets during the filming process. It’s also the name of another Daphne Du Maurier character. Hammer deserves contempt for cheating on his wife but James shouldn’t escape criticism either (via Cinemablend).

Ben Affleck and Emily Ratajkowski

Most people know Ratajkowski as one of the world’s most famous models. But she also dabbled in acting and had a supporting role in the hit thriller, Gone Girl. She worked with notorious womanizer Afflect and reportedly had an affair with him. This also meant that he would have cheated on his ex-wife, Jennifer Garner.

Remember, Affleck is the type of man who cheated on Jennifer Lopez with strippers. This is not outside the realm of possibility. It’s also a fact that he handpicked Ratajkowski for the role with many suggesting that he knew what he was doing. Affleck and Garner divorced in 2018 (via THG).

Daniel Craig and Rachel Weisz

Craig and Weisz maintain an intensely private marriage but that shouldn’t surprise anybody. They worked together as co-stars in 2011’s Dream House. Both of them were in long-term relationships at the time but this didn’t stop them from having an alleged affair on the set.

Often, cheating doesn’t work out but this seems to be a rare exception. Craig and Weisz accepted that they were right for each other and didn’t want to lie to their partners. The fact that they’d been together for almost 15 years suggests that this was the right call (via Us Magazine).

John Malkovich and Michelle Pfeiffer

Malkovich and Pfeiffer met on the set of Dangerous Liaisons but they took the theme of forbidden love too far. They both had unhappy marriages and Malkovich was on the brink of a divorce. When he met Pfeiffer it was too difficult not to fall for a beautiful, kindred spirit (via Best Life Online).

Director Stephen Frears explained: “Dangerous Liaisons is about betrayal and lies and relationships unraveling. It was one of those times where reality and art intersect. But it was overwhelming for John. Even for a man who delights in bad behavior, that was a difficult time.”

Brad Pitt and Angelina Jolie

Here’s one of the most notorious celebrity relationships ever. Pitt has a history of dating co-stars but took it too far when he cheated on Jennifer Aniston with Jolie. Aniston filed for divorce after he worked with Jolie on Mr. And Mrs. Smith in 2005.

Chemistry sparked when they filmed together on-set and they even vacationed together. However, in 2016 Jolie filed for divorce after things turned bad between them. Their cheating scandal was a huge news story at the time because they were two of the most powerful actors on the planet (via Red Book Mag).

Sydney Sweeney and Glen Powell

Rom-com fans can’t get enough of Sweeney and Powell’s on-screen chemistry. The gorgeous duo left pulses racing when they worked together in Anybody But You. Then Powell’s partner Gigi Paris left him sparking cheating rumors. However, the pair vehemently deny anything untoward happened.

“That’s obviously not true,” Sweeney told the world on SNL (via InStyle). “Me and my fiancé produced the movie together, and he was there the entire shoot. I just want to let everyone know that he’s the man of my dreams, and we’re still together and stronger than ever.”
