In a recent, candid interview with Details magazine, Shia LaBeouf admitted, after much speculation, to hooking up with his co-star Megan Fox on the set of Transformers.

Shia said in the interview:

“Look, you’re on the set for six months, with someone who’s rooting to be attracted to you, and you’re rooting to be attracted to them. I never understood the separation of work and life in that situation. But the time I spent with Megan was our own thing, and I think you can see the chemistry onscreen.”

And what about Fox’s current husband, Brian Austin Green? Were they dating at the time? Shia responded with, ”I don’t know, man. I don’t know. I don’t know. I don’t know … ” he says, repeating ‘I don’t know’ 12 times, in 12 different ways before finally saying, “It was what it was.”

An on-set source also confirmed that Shia and Megan were romantically involved on set:

“Yes, Megan and Shia hooked up. It was when Megan and Brian broke up. They had a 10-month break before getting back together.”

“[Shia and Megan] bonded while filming. Believe me, that was an unhappy set. I think they were drawn together because it was so ugly working on that film.”

The truth always comes out on these situations. I wonder how Megan feels about Shia spilling the beans? I figure we’ll hear from her sooner or later.
