In a development that everyone saw coming, Isabel Lucas and Adrian Grenier have split up, following her 3am car crash with Shia LaBeouf.

The pair broke up about three weeks ago, right after the accident that left LaBeouf with a crushed hand. “It wasn’t working out,” says a source. “Adrian saw her with Shia and that was kind of it – the crash, their hanging out. He obviously didn’t appreciate it.”

Lucas, 22, was the passenger in LaBeouf’s car. She was treated for minor bumps and bruises at the hospital and released.

Lucas’s rep confirmed to People that the actress “is single.”

Adrian ‘didn’t appreciate’ his girlfriend hanging out with her co-star at 3am. That seems to be underplaying it a little. While she could have a reasonable explanation for the outing (“I needed a ride home and Shia’s known for being a responsible driver!”) it’s possibly the way the situation was handled that led to the break up. No ones likes to be confronted and challenged about their actions, and that could have led to arguments that ended the relationship, rather than any actual relationship between Isabel Lucas and Shia LaBeouf.

Of course, they could be shagging up a one handed storm right now.

Shia’s pinkie, that was supposedly at risk of amputation, is the only finger on his injured hand not bandaged. Clearly, it is still well attached in these pictures. Possibly it was going to be attached to replace another injured digit (yes, this does happen) but he seems to have a full set. This is great news, although I was slightly curious to see how a missing finger would affect his career. I think he could be excluded from roles because of it. Unless the role is as a pianist, I don’t really think it matters if he has only 9 digits.
