This is not actually accurate.
Of everyone here, Jo is the only one who has spent any real time with Emma, and who may have a clue about her real life. Unlike people who think they know everything after reading tabloids and books. Maybe you should listen to her instead of making snarky remarks.
Now, even if those were Jonny words instead of Jo ones I would believe it... Because come on, even people who work for the Queen are allowed a day-out now and then! Movie-makers (directors and everybody) are still people, still human, they are not gods - and what hapens if Emma gets a crazy flu and can't leave her bed? You think it will ruin the movie? They will just put the shooting for the week after, and do something else till then...
Crazy obsessive fans, duuh
Cheers to Jo, for stating the obvious for the unfortunate ones that need to hear it but still ignore anyways... bleah
