Hiding Admin Public Meta Data

I post author meta data (name, description, url, etc.. ) on a single post template, for a member based listing site.

While most of the generated posts are by members, some are made by the admin.. and as such I would like to hide the meta data when a post’s author is admin.

currently this is outside the loop in my single.php template

<?php
    $curauth = (isset($_GET['author_name'])) ? get_user_by('slug', $author_name) : get_userdata(intval($author));
    ?>
<?php echo $curauth->user_nicename; ?>
<?php echo $curauth->user_description; ?>
<?php echo $curauth->user_url; ?>

how can I edit this to hide the info when the author is admin?

I tried looking at running a conditional tags thing, but didn’t find anything for single posts.. only author pages.

any help will be greatly appreciated.

Thanks
