In my opinion, it will not be a good idea, instead of getting an explanation for the delay in your application process, you might have to give explanation from where you got her email address (unless you got it directly from her). Some people might take offence on this matter and if you have to reveal the name of the person from whom you got the email (which I assume you will not reveal
), it could lead to possible delays for both the applications.
I would say, hold your horses, let things happen in its due course. If you want to enquire about the status of your application, you can always send an email with your file number to the email which is in public domain.
