15 Times We Wondered If These Married Celebs Ever Cheated With Their Co-Star

We’re all familiar with celebrity affairs. These scandals take up a decent amount of our time, because they are constantly flooding the newsstands or our newsfeeds. In addition to being super juicy and full of drama—which we are all easily entertained by—they are extremely common. Celeb relationships aren’t known for their longevity, and their participants aren’t known for their faithfulness.

Not only do we see plenty of celeb affairs happening, but we also wonder if others have happened, too. It’s definitely a challenge to keep up with all of the celebrity relationships going on. The main reason that we may be aware of cheaters is because the details were just too juicy and had to go viral. There are still quality affair stories that don’t push their way to the top of the list of most interesting news.

As we all should know by now, no celebs are necessarily safe when it comes to avoiding unfaithfulness. Stars are around so many people, from fans to fellow celebrities. For example, what if two separately married stars were working very closely together on a movie? We would likely make some assumptions, and we would also do a Google search to find out more. Celebs can’t slide anything past us, can they?

Well—as it turns out—there are tons of celebs who might have or actually did cheat on their partners with a co-star. Let’s dive in and find out more about these sneaky relationships!

15 Johnny Galecki And Kaley Cuoco

Johnny Galecki and Kaley Cuoco starred in The Big Bang Theory together, but there might have been something going on outside of the TV show. There was naturally some speculation about a potentially secret relationship between the two actors.

Eventually, these rumors were proven true. The two dated for a little while following the announcement, but it came to a close pretty quickly. They just could not work things out. Could this have been a cover-up though?

Then, Cuoco married someone else, and Galecki ended up in various relationships. Before too long, Cuoco’s marriage ended. There are some people who believe that she might have gotten caught cheating on her spouse with Galecki. There is also a chance that the actors got back together after Cuoco’s divorce, but it was kept on the down-low if it happened.

14 Harrison Ford And Carrie Fisher

Those of us who are fans of the Star Wars series probably wouldn’t even see this one coming. Because it happened such a long time ago, these cheating rumors didn’t necessarily make headlines recently. It actually was made public in 2016 though.

When Harrison Ford was filming Star Wars in 1977, he was married to Mary Marquadt. The couple even had two kids together. She wasn’t the only lady in Ford’s life though, because it is said that he had an affair with Carrie Fisher. Keep in mind that Fisher was 19 at the time, making Ford 14 years older than her. Fisher and Ford entered into a three-month affair while filming, but it was terminated when they flew back to their homes. Ford later got a divorce from Marquadt, but it supposedly didn’t have to do with Fisher.

As many of us know, Fisher passed away in 2016. The information about the affair was noted in her memoir.

13 Ryan Phillippe And Abbie Cornish

Ryan Phillippe was originally married to actress Reese Witherspoon. Witherspoon and Phillippe got married at a young age, and this marriage proved to be a short-term deal. They did manage to last through eight years and two kids though.

Their relationship began going downhill with Phillippe’s role in Stop-Loss. Shortly after he began filming for this movie, rumors began circulating. It was believed that he was cheating on Witherspoon with his co-star, Abbie Cornish.

Phillippe and Cornish repeatedly denied these claims, but Witherspoon and Phillippe ended up getting a divorce. Strangely soon after the divorce was made official, Cornish and Phillippe publicly announced their relationship. After three years together, Cornish and Phillippe split too. Maybe he got caught wrapped up in an affair, and she called the whole thing quits.

12 Chris Pratt And Jennifer Lawrence

Many of us know that Chris Pratt was once married to Anna Faris. The couple even have a son together. Pratt and Faris have recently separated though, without sharing an explicit reason.

Though we were never given an answer about the split, there is much speculation when we consider the friendship between Pratt and his co-star Jennifer Lawrence. The two have always seemed to be very close. Lawrence is often blamed for the breakup between Faris and Pratt as well.

Over time, we’ve seen a bond forming between Lawrence and Pratt. They share photos of each other and seem to be somewhat flirty on set. The suspicion there is definitely legitimate, and it quite possibly has a lot to do with Pratt’s separation from his wife. No matter what the cause actually is, we’re sure Faris isn’t too happy to see how well Pratt and Lawrence get along.

11 Johnny Depp And Amber Heard

Johnny Depp and his partner—Vanessa Paradis—had been together for a total of 14 years when their relationship crashed and burned. The pair even had two kids together. They really seemed as if they knew how to maintain a relationship long term.

As it turns out, somebody had to mess it up. That somebody—in this case—happened to be Depp. This all began with his role in The Rum Diary. In this film, he starred alongside Amber Heard. It didn’t take long before rumors went live, claiming that Heard and Depp were having an affair.

Once Depp got a divorce, he began dating Heard publicly and married her a couple of years later. Depp experienced another breakup when he faced abuse accusations from Heard, which resulted in a restraining order.

10 Ben Affleck And Jennifer Garner

Ben Affleck has had his share of fun with various Jennifers over the years. He dated Jennifer Lopez for several months before moving on to Jennifer Garner. There is some question as to whether or not his relationship with Garner was on the up and up. The relationships seemed pretty close to each other, time-wise.

“We met on Pearl Harbor, which people hate, but we fell in love on Daredevil," Affleck claims, about his relationship with Garner. It’s not a great situation from what we can tell. The two began their relationship while filming, but they were each in separate relationships of their own.

Was Affleck actually still with Lopez when he began his relationship with Garner? There seems to be some overlap, so we can easily believe that something shady was going on here.

9 Meg Ryan And Russell Crowe

We have stumbled upon another relationship filled with suspicious behavior. These shouldn’t be too shocking anymore though, just because of their frequency. What’s more surprising is how it all went down.

To kick it off, Meg Ryan was married to Dennis Quaid. While she was in this relationship with Quaid, she was starring in movies. One movie in particular—Proof of Life—led to some pretty big changes for the couple’s struggling marriage.

Russell Crowe was also on the set of Proof of Life, and he and Ryan hit it off. The affair rumors exploded across the media. The news of the affair led to a divorce between Ryan and Quaid. Since Crowe and Ryan began their quick relationship, they have remained pretty quiet about it. They haven’t seemed interested in sharing the slightest bit of information about the affair, but we’re guessing it happened based upon Quaid and Ryan’s divorce.

8 Brad Pitt And Angelina Jolie

Most of us know the classic story of how Brad Pitt and Angelina Jolie met. From what we’ve seen, it hasn’t been the most effective relationship, and the two have recently split up. Let’s focus on the beginning of their love story for now though.

At the time when Mr. & Mrs. Smith was being produced, Pitt was married to Jennifer Aniston. This relationship came to a close quickly after affair rumors began circulating about Pitt and Jolie. These rumors claimed that Jolie and Pitt had been fooling around on the set of Mr. & Mrs. Smith.

Of course, Pitt and Jolie were quick to deny the claims—as most celebs are. Suspiciously enough, Pitt and Aniston split up. This gave Pitt and Jolie the chance to become an official couple, and they ran with it!

7 Chris Pratt and Bryce Howard

Chris Pratt doubled on up on the ladies once again—and we can’t say we are surprised. We just thought he would have figured his life out at some point and taken a break from people who aren’t his wife.

While Pratt was supposed to be hard at work filming Jurassic World, he was apparently also working to fall in love with Bryce Howard. Howard acted alongside Pratt throughout Jurassic World: Fallen Kingdom, and the two became close pals. It’s said that Howard was so sad at the end of the filming period that she cried and gave Pratt a crazily tight hug.

Yet again, Faris is left with a husband who just likes to build super close bonds with his co-stars. As mentioned before, it’s lucky that Faris and Pratt ended up splitting, but we’re guessing his friendliness toward women has something to do with it.

6 Chad Michael Murray And Paris Hilton

After Chad Michael Murray’s marriage began as a result of an on-set romance, he must have assumed it was totally acceptable. Murray was first married to Sophia Bush, who was his co-star on One Tree Hill, a TV show. Unfortunately for them—and for the show’s fans—the relationship quickly fell apart.

Keeping with his pattern of getting with co-stars, Murray hooked up with Paris Hilton on the set of House of Wax. As soon as this affair became public, Bush left Murray. She ended up getting an annulment on their marriage, and she made sure that she said some not-so-nice things about Murray throughout the process.

The worst part about this rocky breakup is that Murray and Bush still had to be cordial to each other when continuing to film One Tree Hill after they split.

5 Ryan Gosling And Emma Stone

We all love the heartthrob Ryan Gosling, and most of us would die for a simple chat with the guy. As it turns out, Emma Stone is one of us! She comes across as someone who is also crushing on Gosling—and we don’t blame her.

Luckily for Stone, she’s gotten to star alongside Gosling in multiple films. They sometimes even play a cute couple together in these movies. That chemistry also shows off-screen. The big problem with their lovey friendship is that Gosling is already married. Eva Mendes—Gosling’s wife—probably isn’t too happy about his close relationship with Stone.

After hearing that Mendes and Gosling haven’t always been on the best terms, we’re voting for Stone and Gosling to get hitched. We’re pretty sure that the duo has already hooked up among other things.

4 Steve McQueen And Ali MacGraw

This is another one of those affairs that was buried deeply under Hollywood’s history. These gems are tricky to find, but they are full of details that we would never expect. We have always thought that the stars who were making movies back then were classier and had higher standards. Apparently, cheaters have few boundaries.

In summary, Steve McQueen and Ali MacGraw had a pretty terrible affair. By this, we mean that the affair wasn’t only bad for Robert Evans, who was MacGraw’s then-husband. MacGraw and McQueen met on the set of The Getaway. It started with MacGraw falling for her co-star and then leaving Evans. We’re thankful she at least had to decency to eventually be honest with her former husband. MacGraw and McQueen ended up getting hitched.

Their marriage lasted only five years and was filled with cheating scandals by McQueen.

3 LeAnn Rimes And Eddie Cibrian

While LeAnn Rimes was married to her husband—Dean Sheremet—she was tempted by some other eye-candy. Sheremet and Rimes had been married for seven years at this point, but that wasn’t enough to stop her from making a move.

While Rimes was filming a movie—Northern Lights—she met Eddie Cibrian. The two worked together on the movie, and they eventually hooked up. To make it all worse, Cibrian was married to Brandi Glanville and even had two kids with her at the time.

According to the cheaters’ spouses, the affair was very open. Cibrian and Rimes apparently flirted in front of their spouses and weren’t attempting to keep it a secret. Cibrian and Rimes got married two years after beginning their relationship, but Glanville has shared that Cibrian has gone back to her several times.

2 Marilyn Manson And Evan Rachel Wood

When Marilyn Manson was in a pretty serious relationship, he stepped out of bounds and got himself into some trouble. At the time, he was dating Dita Von Teese. Von Teese was a lingerie model, while Manson—as many of us know—was a musician.

Manson’s relationship with Von Teese went downhill when he was working on a music video. In the music video—Phantasmagoria: The Visions of Lewis Carroll—Manson worked closely with Evan Rachel Wood.

Shortly after Wood and Manson began working side by side, there were rumors spread that the two had even hooked up on the set of the video. Sure enough, that was enough for Von Teese to break it off with Manson. Then, Manson and Wood got engaged. They didn’t end up getting married though, because Wood left him.

1 Daniel Craig And Rachel Weisz

Let’s get some background on yet another double affair. What’s going on with all of these already-married people hooking up with each other? It seems strange that it has become so common!

To start off, Rachel Weisz was with Darren Aronofsky. The two had been together for a total of nine years and were still going strong—or so it seemed. Daniel Craig had been dating his girlfriend—Satsuki Mitchell—for seven years when this all went down. Each couple also had a child.

Weisz and Craig were filming Dream House together when they ended up hitting it off. As soon as filming was officially completed, the duo was also officially dating. They ended up getting hitched and have remained behind the curtains ever since. They seem to live pretty secretive lifestyles.
