Megan Fox's representative has confirmed the actress became romantically involved with Shia Labeouf on the set of Transformers, after he went public with the fling earlier this week.

LaBeouf refused to go into details over the romance with his co-star, but he hinted during an interview that they became more than friends on the set.

Speaking to Details magazine, he said, "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... It was what it was."

The actor insists he's unaware if Fox was dating her now-husband Brian Austin Green at the time of their tryst, and the actress has so far kept quiet about the speculation.

But now her publicist has confirmed LaBeouf's revelations, telling the New York Daily News, "It is true."
