Three unnamed workers on the action movie posted an open letter supporting Bay on his official website after Fox lashed out at him in a recent interview.
The 23 year old compared the director to Hitler in an interview with Britain's Wonderland magazine, and told how he had "no social skills" and is "hopelessly awkward."
But some Transformers crew members took exception to the comments, and slammed the actress' own on-set behaviour.
They describe "the tedious experience of working with the dumb-as-a-rock Megan Fox," and insist they "had the unbearable time of watching her try to act on set."
They also brand Fox "as ungracious a person as you can fathom," and complain she refused to thank them when they had "to deal with the awful silly Marilyn Monroe tattoo plastered on her arm that we cover up."
But Bay was unimpressed with the letter - it was removed from his website on Saturday (12Sep09) and replaced with a piece from the director himself, defending Fox and insisting her negative comments are part of her "crazy charm".
He writes, "I don’t condone the crew letter to Megan. And I don’t condone Megan’s outlandish quotes. But her crazy quips are part of her crazy charm. The fact of the matter (is) I still love working with her, and I know we still get along. I even expect more crazy quotes from her on Transformers 3."
