Let’s be real for a second. If you grew up in the late 2000s, there was no bigger cinematic pairing than Sam Witwicky and Mikaela Banes. It wasn’t just the giant robots or the explosions. It was the crackling, high-voltage energy between the two leads. For years, people speculated. Was it just good acting? Or was something actually going on when the cameras stopped rolling?
The answer, as it turns out, was a resounding yes.
The 2011 Bombshell That Started It All
It took years for the truth to trickle out. In a 2011 interview with Details magazine, Shia LaBeouf basically dropped a tactical nuke on his own reputation for privacy. When asked if he had hooked up with Megan Fox, he didn’t give a PR-friendly "no comment." He gave a "look, you're on set for six months with someone who's rooting to be attracted to you, and you're rooting to be attracted to them."

He didn't stop there.
He admitted he never understood how to separate work and life in that kind of high-pressure environment. To him, the chemistry you saw on that IMAX screen wasn't just movie magic. It was real.
But there was a catch. Megan was famously in a long-term, on-again-off-again relationship with Brian Austin Green during that entire era. When the interviewer pressed Shia on whether Megan was with Brian at the time of their "showmance," Shia didn't deny it. He just repeated "I don’t know" twelve times. Literally. Twelve times.

Megan Fox Sets the Record Straight
For a long time, Megan stayed quiet. She had bigger fish to fry, like being blacklisted from the franchise after that infamous "Hitler" comment about director Michael Bay. But in 2018, she finally sat down with Andy Cohen on Watch What Happens Live.
During a game of "Plead the Fifth," the truth came out. "I mean, I would confirm that it was romantic," she said, looking remarkably unfazed. She went on to say that she loves him and has never been quiet about that.
It’s interesting, right? Most Hollywood flings are buried under NDAs and "just good friends" platitudes. Not this one. Megan described it as a "showmance"—something intense that lives and dies within the bubble of a movie production. Once the trailers are packed up and the pyrotechnics are extinguished, the reality of life (and pre-existing partners) usually sets back in.
Why This Connection Actually Matters
Look, Hollywood is full of people who can't keep their hands off each other. So why do we still care about this specific pair in 2026?
- The Power Dynamic: Shia and Megan were the "It" kids of the mid-2000s. They were young, incredibly famous, and working under Michael Bay, a director known for making everything feel like a high-stakes adrenaline rush.
- The Fallout: Shortly after the second movie, Megan was gone. Rosie Huntington-Whiteley stepped in, and the vibe changed completely. The Shia-Megan dynamic was the soul of those first two films.
- The Human Element: It’s a reminder that actors aren't robots. When you spend 14 hours a day in the desert being "in love" for the camera, the lines get blurry.
The Brian Austin Green Factor
We can't talk about this without mentioning the "elephant in the room": Brian Austin Green. He and Megan started dating when she was just 18 and he was 30. They were together for a huge chunk of her career.
Rumors have circulated for years that the Shia-Megan fling caused major friction. Some reports suggest Brian was "freaked out" by their continued closeness even after the filming ended. While they eventually married and had three children, that period of her life remains a messy, complicated footnote in their decade-long history.
What Happened After the Cameras Stopped?
By 2011, when Shia did that interview, he was already moving on to other relationships, like his time with Carey Mulligan. Megan was trying to navigate the wreckage of her Transformers exit.

They didn't end up together. Life isn't a Michael Bay movie.
Shia eventually went through a series of public highs and lows, including a high-profile conversion to Catholicism and various legal battles. Megan, meanwhile, moved on to a very public relationship with Machine Gun Kelly. But even today, if you watch those original movies, you can see what they were talking about. That spark wasn't manufactured by a CGI team at ILM.
Key Takeaways for Fans
If you’re trying to wrap your head around this Hollywood saga, here is the basic reality:
- It was real, but brief. Both stars have confirmed the romance was limited to their time on the Transformers sets.
- Timing was messy. It overlapped with Megan's relationship with Brian Austin Green, though the exact "break" status during the fling remains a bit of a gray area.
- No bad blood. Despite the controversy, both have spoken fondly of each other in the decades since.
If you want to understand the modern celebrity landscape, look at how this story was told. It wasn't a PR leak; it was two people being surprisingly honest about the weird, blurry reality of being young and famous.
The next time you're re-watching the first Transformers, pay attention to the scene where they're looking under the hood of the Camaro. Knowing what we know now, the heat in that scene makes a whole lot more sense.
Actionable Insight: If you're interested in the psychology of "showmances," look into the "Propinquity Effect." It’s a psychological phenomenon where people form bonds simply because they are physically near each other for long periods. It explains why so many movie sets result in real-life romances, regardless of who is waiting at home.
