Well, as I understand the situation, David Hayman knows that Gillian is with somebody. He knew it 18 months ago, he knows it now. *cough David cough* He only didn’t know what status of this relationship is because probably he isn’t close to her that much and he « assumed » that she must be married. It totally could have happened that way and honestly is the only rational explanation. I heard that the whole Hollywood knows about G and D. Well, even Hariss’ assistant knew it! This is not a secret!!!
