Scandalous affairs are hard to hide, especially from the public eye. This doesn’t make infidelity any less common amongst celebrities. Here are 15 stars who opened up about their reasons for cheating on a partner.
1. Demi Moore cheated on Freddy Moore just hours before they got married. While most brides opt for beauty sleep the night before their big day, Moore snuck out to get busy. Demi was just 18 years old on the eve of her first wedding to musician Freddy Moore. Dealing with the death of her father, burgeoning fame, and an intense relationship, she saw cheating as an escape. In her 2019 memoir Inside Out, Moore wrote about her evening of infidelity.
“The night before we got married, instead of working on my vows, I was calling a guy I’d met on a movie set,” Moore revealed. “I snuck out of my own bachelorette party and went to his apartment.”

“Why did I do that? Why didn’t I go and see the man I was committing to spend the rest of my life with to express my doubts? Because I couldn’t face the fact that I was getting married to distract myself from grieving the death of my father,” she wrote. “Because I felt there was no room to question what I’d already put in motion. I couldn’t get out of the marriage, but I could sabotage it.”

2. David Boreanaz compared his desire to cheat to a “demon” possessing him. Boreanaz told E! News, “In a sacred ground like marriage, you find yourself out of it at certain times for reasons unknown that can be destructive. There could be a demon that kind of comes out and overtakes you.”

3. Jesse James cheated on Sandra Bullock as a method of self-sabotage. Just after winning her Academy Award for her performance in The Blind Side, Bullock filed for divorce. Her split from motorcyclist and Monster Garage star, Jesse James, was a product of his infidelity. James revealed in a Nightline interview with ABC News that his cheating was a result of the child abuse he faced. “Bike builder, Monster Garage TV star…all that stuff is a huge smokescreen so that people won’t see that I’m a scared, abused kid. A 7-year-old,” James admitted.

He later revealed to ABC News, “I think I do things to sabotage my life, including having extramarital affairs, texting, overworking myself, injuring myself, doing stunts and stupid things. I think I do a lot of things in my life that I shouldn’t be doing that aren’t conducive to being a perfect husband, you know, and the affairs are just one of them.”

4. Tristan Thompson claims he was unfaithful to Khloe Kardashian because he didn’t have a healthy example of love growing up. On an episode of The Kardashians, Thompson sat down with Kourtney Kardashian to explain his side of the story. He admitted to her, “I was just cheating for an action, just cheating for a feeling, but also it really came down to not knowing how to love, because that’s the way I grew up.” Seeking an emotional Band-Aid from an affair to heal the wounds of childhood trauma proves to be a common thread amongst cheaters.

5. Speaking of Kardashians, Kris Jenner cheated on Robert Kardashian to see if there were better options out there. In a heart-to-heart with Khloe Kardashian, Kris opened up about a mistake from her past. Jenner shared, “I thought that the grass was greener somewhere else, and I made a huge mistake. That’s my life’s biggest regret.” She also admitted that being young and not understanding the repercussions of her actions was a driving factor in her decision to cheat. Jenner isn’t the only one who thinks that her age influenced her infidelity.

6. Claire Danes had an affair with Billy Crudup because love blinded her perception of the consequences. In 2003, Crudup left his pregnant partner of eight years, Mary-Louise Parker, to be with Danes. Danes also ditched her partner of six years, Ben Lee, to pursue Crudup in an affair that would dominate press coverage. It was so scandalous that Crudup even wrote a letter to The New York Times, begging society to stop fixating on his relationship(s).

Looking back on her affair with Crudup, Danes can see things clearly now. In a 2015 interview on The Howard Stern Show, she remarked, “I was just in love with him, and needed to explore that, and I was 24…I didn’t quite know what those consequences would be.”

7. In the long lineage of reality stars who’ve cheated, Tom Sandoval links his infidelity to Ariana Madix with his party lifestyle. Sandoval’s cheating scandal, A.K.A. “Scandoval,” has followed him across networks from Vanderpump Rules to America’s Got Talent to The Traitors. His reputation for a nine-year relationship with one Vanderpump costar (THE Ariana Madix), and a simultaneous affair with another (Rachel Leviss), is notoriously messy.

On his podcast, Everybody Loves Tom, he revealed what was going on in his personal life during the time of his affair. “I was on a path that was not great. I was drinking all day, every day. I was chain-smoking cigarettes, going out constantly…chasing the dragon, running away from everything and hiding, hiding, hiding,” he explained. He certainly isn’t the only celebrity who’s blamed his affair on a bad mental state…
