Here's the structure of $vbulletin->blogstats, with junk from my test server.

Array
(
    [lastentry] => Array
        (
            [username] => Kevin
            [userid] => 1
            [title] => fdsasdfafsda
            [blogid] => 1
            [categories] => 
            [postedby_username] => Kevin
            [postedby_userid] => 1
            [blogtitle] => 
            [guestcanview] => 1
        )

    [total_blog_users] => 1
    [total_blog_entries] => 1
    [entries_in_24hours] => 1
)

So you probably want something like:

require_once(DIR . '/includes/blog_functions_shared.php');

if (is_array($vbulletin->blogstats) AND is_array($vbulletin->blogstats['lastentry']))
{
   $user = $vbulletin->blogstats['lastentry']['username'];
   $userid = $vbulletin->blogstats['lastentry']['userid'];
   $title = $vbulletin->blogstats['lastentry']['title'];
   $url = '<a href="' . fetch_seo_url('entry', array('blogid' => $vbulletin->blogstats['lastentry']['blogid'], 'title' => $title))	. 
			"\">" . $title . '</a>';
}
