Ouch. Megan Fox really messed with the wrong people right at the height of her career. It's just been revealed that the real reason the sexy Transformers star was replaced in the third installment of the series is because Steven Spielberg (who is the executive producer of the films) demanded that she be fired after she compared her director, Michael Bay, to Hitler.

She had said of Bay in an interview with Wonderland Magazine in 2009:

"He's like Napoleon and he wants to create this insane, infamous mad-man reputation. He wants to be like Hitler on his sets, and he is. So he's a nightmare to work for but when you get him away from set, and he's not in director mode, I kind of really enjoy his personality because he's so awkward, so hopelessly awkward. He has no social skills at all. And it's endearing to watch him."

When that little gem was published, Michael Bay recalls getting the following instructions from Spielberg: "You know the Hitler thing. Steven (Spielberg) said, 'Fire her right now.'"

And fire her he did, replacing Fox with Victoria's Secret model Rosie Huntington-Whiteley, who is now the sexpot of Transformers: Dark of the Moon, in theaters June 29th.

Fox's career hasn't been the same since.

Like her, we've probably all had a complaint or two about our bosses or co-workers -- it's a part of the working world (though, Fox's remarks were particularly distasteful and thoughtless). Granted, we don't have to give interviews to magazines about our jobs and the people we work with, but we can make the same rookie mistake of saying something to someone we shouldn't.

In that regard, do you feel a little sympathetic for Megan Fox for putting her foot in her mouth, or not? Have you ever made a similar mistake of bad-mouthing your boss, and what did you learn from that experience?
