Megan has blown apart Hollywood's casting couch culture - insisting several leading film directors have tried to bed her since she found fame.
The Transformers beauty has attended a number meetings with top moviemakers to discuss potential roles.
But she was shocked when they made moves on her during the interviews - and immediately turned them down.
Fox, who refuses to name names, tells Britain's GQ magazine, "Any casting couch s**t I've experienced has been since I've become famous. It's really so heartbreaking. Some of these people! Like Hollywood legends.
"You think you're going to meet them and you're so excited, like, 'I can't believe this person wants to have a conversation with me,' and you get there and you realize that's not what they want, at all. It's happened a lot this year actually."
And Fox also has a way of dealing with male co-stars who flirt with her - she delivers a damaging blow to their ego in front of the entire crew.
She says, "There are some guys, talking about actors who have been in the business for a while, who are very egocentric and have been able to sleep with a lot of girls for whatever reason, and because they don't know me they think I'm going to be this little cupcake, this Marilyn Monroe type who's going to bat my eyes and be like a receptacle for them.
"I just shut them down immediately, right in front of people. It's been so long since someone has told them no, they don't really know how to deal with it. Because of this non-reality they live in, they're f**ked up, psychologically."
