In his new feature for DETAILS magazine, Hollywood bad boy Shia LaBeouf recently revealed that his former Transformers co-star Megan Fox let him explore her “inner regions” while the two were filming their blockbuster hit.

During the interview, the interviewer asked point blank if Shia ever hooked up with Fox … and according to the article, “LaBeouf nods affirmatively.”

The alleged fling took place on the set of the original Transformers flick and according to Shia you can see the result of their bedroom chemistry on-screen.

“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.”

If Shia’s loose lips aren’t bad enough - - - the actual shocking part of the article comes when the interviewer says he asked if Megan was dating her current husband Brian Austin Green during their hookup … and LaBeouf replied,

“I don’t know, man. I don’t know. I don’t know. I don’t know. . . .”

Finally closing out with:

“It was what it was.”

Damn….let me find out Shia got a little “gangsta” in him lol.

Thoughts??
