Everyone has that one friend whose relationship is a total car crash, right? You want to look away, but you just can't. For the last few years, that friend has been Megan Fox and Machine Gun Kelly. Their "twin flame" saga has involved everything from drinking each other's blood to wearing thorns on engagement rings. But the question that keeps popping up is pretty old-school: did Machine Gun Kelly cheat on Megan Fox?
The answer isn't a simple yes or no. Honestly, it’s a mess of cryptic Instagram posts, "material" found on phones, and very public denials.
The Night Everything Blew Up
It started on Super Bowl weekend in 2023. Megan Fox did what every millennial woman does when she’s fed up—she scrubbed her Instagram. She deleted almost every trace of MGK (real name Colson Baker) and then posted a mirror selfie with lyrics from Beyoncé’s Pray You Catch Me. You know the one. "You can taste the dishonesty / it's all over your breath."
If you're quoting Lemonade, you aren't just "having a disagreement." You’re signaling infidelity.
Social media went into a full-blown meltdown. Within hours, fans pointed fingers at Sophie Lloyd, the talented guitarist in MGK’s band. Why? Basically just because she was a woman in close proximity to him. It was a classic "blame the other woman" move that lacked any actual receipts. Megan later had to step back into the fray to clear Sophie's name, calling her "highly talented" and telling everyone to leave her alone.

What Megan Actually Said
Megan Fox eventually reactivated her account to drop a Notes app screenshot. She was firm. She said there was "no third party interference" in the relationship. No DMs. No AI bots. No succubus demons.
That seemed to settle it. For a while.
The 2024 Shift: New Rumors, New Drama
Fast forward to late 2024, and things took a darker turn. Reports started circulating that they had split—again—but this time it was more serious. Megan was pregnant with their daughter, Saga Blade Fox-Baker (who was born in March 2025).
Insiders claimed Megan found something "upsetting" on MGK's phone during a trip to Vail. Some sources used the word "flirtatious." They alleged MGK was being way too friendly with people in his DMs.
Was it physical cheating? Maybe not. But for Megan, it seemed to be a massive breach of trust. When you're pregnant and you find "material" on your partner's phone that makes you want to pack your bags and leave a vacation early, the label doesn't really matter. It feels like cheating.
- The Phone Material: Sources told TMZ and Us Weekly that the content Megan saw was the "final straw."
- The Denial: MGK has reportedly denied ever actually sleeping with anyone else.
- The Outcome: They called off the engagement and, by most accounts, moved into separate houses.
Where They Stand in 2026
It is now January 2026, and the dust has somewhat settled. If you’re looking for a romantic reunion, you’re probably going to be disappointed. While they were spotted together on a "reconciliation retreat" in Costa Rica back in mid-2025, they haven't officially gotten back together.

They are currently what you might call "professional co-parents." They've been seen at the L.A. Zoo and the Getty Center with their daughter, Saga. MGK is reportedly at Megan's house almost every night to help out, but they aren't sleeping in the same bed. Megan has been very vocal about "owning her boundaries" this year. She learned the hard way that their relationship was "not for public consumption."
Why the Cheating Rumors Still Matter
The reason people still ask if he cheated is because their relationship has always been built on intensity. When that intensity turns into "trust issues," it's hard to get back to a baseline. In her interview on the Call Her Daddy podcast, Megan admitted they had been through a lot of things that were "confusing" to outsiders.
She hasn't explicitly labeled him a "cheater" in a traditional sense, but she has acknowledged that the trust was broken.
Actionable Takeaways from the Fox-MGK Saga
If you’re following this story because you’re dealing with your own "twin flame" drama or trust issues, here are a few things we can learn from how they handled it:
1. Public scrubbing rarely helps. Megan deleting her Instagram sparked a global witch hunt against an innocent guitarist (Sophie Lloyd). If you're mad, maybe put the phone down before you go nuclear on social media.
2. Define your "third party." Infidelity isn't always a physical act. For Megan, "flirtatious DMs" were enough to end an engagement. It's important to have a clear conversation with your partner about what constitutes a deal-breaker before it happens.
3. Boundaries are okay. You can be a great co-parent without being in a relationship. In 2026, Megan and MGK seem more stable as "exes who get along" than they ever did as a couple.
4. Trust your gut. If you find something on a phone that makes you feel sick, don't let anyone gaslight you into thinking it's "just DMs." Trust is the foundation; once it's cracked, it takes years—and often professional help—to fix.
The "twin flame" may have flickered out for now, but the way they are navigating their post-split life in 2026 shows a level of maturity that was definitely missing during the blood-drinking days. Whether or not he "cheated" in the literal sense, the relationship died because the trust was gone. And sometimes, that's all you need to know.
