"Adrian saw her with Shia and that was kind of it," a source told People. "The crash, their hanging out. He obviously didn't appreciate it." They added: "It wasn't working out." A representative for Lucas confirmed that she "is single".
Coincidentally, Shia’s recent appearance with Lucas comes around the same time as the news of her recent break-up. According to Us Weekly, the actress’ shaky relationship with Adrian Grenier ended for good after the accident last month. “All that stuff that happened with Shia definitely didn’t help things. When Adrian saw Isabel with Shia, he knew it was time to move on and made the decision to end things. He’s not upset and thinks Isabel is a really sweet girl but they’re done,” said a source.
Did Grenier sense that Isabel was more than just friends with Shia? Or did the 22-year-old just seem too immature for him at that point? (Adrian is 32.) I’m guessing it was a combination of both.
Assuming production gets back on track, we can see Lucas and LaBeouf together on-screen when Transformers: Revenge of the Fallen opens on June 26.
