Only show related posts if there is any, not just if there are tags

    Basically in my template I have a piece of code which shows the ehading related posts based on if there is any tags in the post. Some posts have tags but no matching/rleated ones so the heading shows with nothing underneath and this is un tidy.

    Trying to figure out a clean way of doing this and getting nowhere, basically want the whole lot hidden unless there are matching posts in the tags…here is the code:

    <?php
					//for use in the loop, list 5 post titles related to first tag on current post
					$tags = wp_get_post_tags($post->ID);
					if ($tags) {
					?>
					  <?php _e('Related News', 'minti'); ?>

					<?php  $first_tag = $tags[0]->term_id;
					  $args=array(
					    'tag__in' => array($first_tag),
					    'post__not_in' => array($post->ID),
					    'showposts'=>3
					   );
					  $my_query = new WP_Query($args);
					  if( $my_query->have_posts() ) {
					    while ($my_query->have_posts()) : $my_query->the_post(); ?>
					      <a href="<?php the_permalink() ?>" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?> (<?php the_time(get_option('date_format')); ?>)</a>
					      <?php
					    endwhile;
					    wp_reset_query();
					  }
					}
					?>

			<?php } ?>

    move this code <?php _e('Related News', 'minti'); ?> to after the if of the main loop;
    example:

    <?php
					//for use in the loop, list 5 post titles related to first tag on current post
					$tags = wp_get_post_tags($post->ID);
					if ($tags) {
					?>

					<?php  $first_tag = $tags[0]->term_id;
					  $args=array(
					    'tag__in' => array($first_tag),
					    'post__not_in' => array($post->ID),
					    'showposts'=>3
					   );
					  $my_query = new WP_Query($args);
					  if( $my_query->have_posts() ) {
					   _e('Related News', 'minti');
					    while ($my_query->have_posts()) : $my_query->the_post(); ?>
					      <a href="<?php the_permalink() ?>" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?> (<?php the_time(get_option('date_format')); ?>)</a>
					      <?php
					    endwhile;
					    wp_reset_postdata();
					  }
					}
					?>

    Thanks, made a few ammendments to display as a heading. Had to close and re open the PHP tags but its working a treat ??

    <?php
					//for use in the loop, list 5 post titles related to first tag on current post
					$tags = wp_get_post_tags($post->ID);
					if ($tags) {
					?>
					  <ul>
					<?php  $first_tag = $tags[0]->term_id;
					  $args=array(
					    'tag__in' => array($first_tag),
					    'post__not_in' => array($post->ID),
					    'showposts'=>3
					   );
					  $my_query = new WP_Query($args);
					  if( $my_query->have_posts() ) { ?>
                                          <h3 class="title"><span>Related News</span></h3>
                                          <?php	while ($my_query->have_posts()) : $my_query->the_post(); ?>
					      <li><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?> <span>(<?php the_time(get_option('date_format')); ?>)</span></a></li>
					      <?php
					    endwhile;
					    wp_reset_query();
					  }
					}
					?>
					 </ul>
			</div>
			<?php } ?>
