Assuming it is really her I'd probably just go ahead and take it down assuming you are just an affiliate. It would make me feel like a creep keeping her content up when she wanted it down.
If you were the shooter or the sponsor then I could see asking for a refund of your payment to her at the very least. Fair is fair.
I agree with the other suggestions that it is a good idea to notify the sponsor/content owner about this. Despite what they said though I personally would still remove the content. As crazy as it sounds from me I don't like pissing off people any more than I have to.
