Mailchimp stylesheets in every page

I am trying to optimise my site to be as efficient as possible and noticed in the code that the stylesheets for MailChimp are in every page whether or not the plug-in is used on that page. Is there any way around this other than coding Mailchimp directly into my theme and dropping the plugin?

I noticed that it calls the stylesheet with a query rather than a direct link which will also add load to the server. There are only a few lines of css but I would like to tidy things up.
