The 66 Most Shocking Celebrity Cheating Scandals of All Time

Continuing on with Vanderpump messes, we have Lala and Randall. After giving birth to their daughter Ocean in 2021, the reality star found out that Randall had been cheating. Like, a lot. "It's been kind of repeated behavior that I have found out about," she told Andy Cohen during an appearance on Watch What Happens Live in January 2022. "And it's not just one person—it's many." She even claimed he moved another woman in with him just two days after she moved out. Ouch.

Okay, so they weren't *technically* celebs when this happened but we're still talking about it, so here goes: When Kris Jenner and Robert Kardashian first got married, their life could have been described as being "straight out of a fairy tale." They were young and in love and welcomed four healthy children together. But, the fairytale life was short-lived. About a decade after their marriage, Jenner had an affair with soccer player Todd Waterman. When the allegations arose, Jenner did not try to deny them and the affair led to Kris and Robert's eventual divorce.

Queen B doesn't really give interviews anymore, but her 2016 album Lemonade told us everything we need to know about Jay-Z cheating on her, including (a) that it happened at all and (b) Beyoncé was PISSED and (c) they worked through it and came out stronger on the other side.

Everyone knows about the on-screen chemistry between Brangelina in Mr. and Mrs. Smith that quickly became IRL chemistry—and that the tabloids had a field day treating poor Jennifer Aniston like a woman scorned. Can't people just let her live?

In March 2016, a video of Iggy's then-fiancé, Los Angeles Lakers basketball player Nick Young, was leaked online, where he admitted to cheating on the "Fancy" rapper. Very rude. After two years together, they ended their engagement in June 2016.

After Gwen Stefani found out that Gavin Rossdale, her husband of 13 years, was reportedly cheating on her with their nanny, she dumped him, got together with The Voice costar Blake Shelton, penned "Misery," and never looked back.

In December 2018, Cardi B and her husband Offset announced that they were getting divorced after a year of marriage. At first, Cardi said that the reason for their split was that they fell "out of love," but then a woman came forward and implied she was one of the reasons for the split.

Cardi and Offset got back together, and she talked to Cosmopolitan about her decision to reconcile, saying, "I want to work out my sh*t with my man, and I don't got to explain why. I'm not your property. This is my life....I’m going to take my time, and I'm going to decide on my decision.…It's not right, what he f*cking did—but people don't know what I did, 'cause I ain't no angel."

Halsey teased that her longtime boyfriend cheated on her when she tweeted and deleted a scissor emoji in July 2018 (which fans theorize was a reference to a lyric from their joint song "Him & I," about what she'd do to G-Eazy's junk if he ever cheated). Months later, Halsey confirmed the fan theory by putting G on blast during her SNL performance, when she sang in front of a backdrop that read "I’m so sorry Ashley [Halsey’s real name] I cheated," and then listed at least a dozen places where the infidelity happened. Yikes!

Kristen Stewart and Robert Pattinson (or as I like to call 'em, KStew and RPatz) were teen royalty when they hit Hollywood together in The Twilight Saga, and their chemistry was palpable (if not completely awkward) in interviews and red carpet appearances. But Kristen later burst the true-love-with-a-vampire-fantasy when she was spotted kissing director Rupert Sanders while filming Snow White and the Huntsman in 2012.

The nanny strikes again—this time possibly splitting up Ben Affleck and Jennifer Garner's marriage. Jennifer opened up about the ordeal in an interview with Vanity Fair, saying that they had been "separated for months" before the scandal and that [the nanny] had "nothing to with our decision to divorce." Hmm. Okay.

Ashton Kutcher and Demi Moore were a power couple back in the good ol' days (you know, the 2000s), but Scott Eastwood dropped a major bombshell in 2015 when he claimed that Ashton had cheated on Demi with Scott's girlfriend at the time—yep, while Ashton was still married to Demi. Woof.

Jada Pinkett Smith and Will Smith have been vocal about their open marriage for some time, so it's debatable if Jada's admitted fling with August Alsina is actually considered cheating. Or, really, we should say her admitted "entanglement." During an episode of Jada's Facebook show Red Table Talk, Will came on as a guest and the two discussed the problems they had been having in their relationship.

When Will asked Jada about rumors about her and August, Jada said, "I got into an entanglement with August." But in an interview with radio host Angela Yee, August explained, "I actually sat down with Will and had a conversation. Due to the transformation from their marriage to (a) life partnership that they have spoken on several times, and not involving romanticism, he gave me his blessing." It's unclear what exactly went down, but at least one thing is true: Jada and August had an entanglement.

After rumors surfaced that pro basketball player Tony Parker had another woman on the sidelines (a former teammate's wife!), the couple split after seven years together.

Kourtney Kardashian and Scott Disick have always had a tumultuous relationship, but things got especially dicey when there were some ~steamy~ photos released of Scott and an ex-flame getting cozy in France. Now she's happily married to Travis Barker, so seems like things worked out.

So while neither Kourtney nor her ex Younes Bendjima have said on the record that their relationship ended because Younes cheated, both Kim and Khloé hinted that was the case. After Younes was photographed hanging out in Mexico with lots of women and then proceeded to slam tabloids on Instagram for implying that he was being unfaithful, Kim commented, "Nice pics from your 'boys trip' 🤥" and Khloé wrote, "Alexa, play 'Heard It All Before' by Sunshine Anderson." So, take from that what you will!

I certainly remember where I was standing when the bombshell news of Arnold Schwarzenegger's extramarital affair with his housekeeper Mildred Baena first dropped. Maria filed for divorce in 2011, after it was revealed that Arnold and Mildred shared a son, Joseph Baena. The divorce was finalized in late 2021, following more than 25 years of marriage.

First we learned that Jesse James had cheated on Sandra Bullock with a stripper who had the words "Pray for us sinners" tattooed on her forehead—and the reveals only got worse from there.

A late-night car crash, an infamous golf swing, and the revelation that Tiger Woods had cheated on his wife of six years was just the tip of the iceberg. Later, we learned that there was way more than one woman. Yikes!
