Both a page loop and posts loop on the same page

Question

I'm trying to get first the content of a single page (the one that is queried), and then in a small section below i want to display the title of my bloggposts as a "Latest News" section.

The problem is that if i first use <?php if ( have_posts() ) while ( have_posts() ) : the_post(); ?> to get the page content. And then try to use $posts_array = get_posts( $args ); to get the blogposts i just get the heading of the page twice. Obviously the get_posts function takes on the id of the page instead of looping through the blogposts. Is there a way to tell get_posts to search for the first 5 blogpost id's and not the current page id?

Grateful for all answers, suggestions, tips or hints :)

here is my code:

<?php if ( have_posts() ) while ( have_posts() ) : the_post(); ?>

            <div class="mcenter">   
                <article id="post-<?php the_ID(); ?>" <?php post_class(); ?> role="article">
                    <header class="entry-header">
                        <h1 class="entry-title"><?php the_title(); ?></h1>
                    </header><!-- .entry-header -->

                    <div class="entry-content">
                        <?php the_content(); ?>
                        <?php wp_link_pages( array( 'before' => '<div class="page-link">' . __( 'Pages:', 'monster' ), 'after' => '</div>' ) ); ?>
                        <?php edit_post_link( __( 'Edit', 'monster' ), '<span class="edit-link">', '</span>' ); ?>
                    </div><!-- .entry-content -->
                </article><!-- #post-<?php the_ID(); ?> -->
            </div>
            <?php endwhile; // end of the loop. ?>

            <?php 
                $args = array( 
                    'numberposts'       => 5,
                    'offset'            => 0,
                    'category'          => ,
                    'orderby'           => 'post_date',
                    'order'             => 'DESC',
                    'include'           => ,
                    'exclude'           => ,
                    'meta_key'          => ,
                    'meta_value'        => ,
                    'post_type'         => 'post',
                    'post_mime_type'    => ,
                    'post_parent'       => ,
                    'post_status'       => 'publish');

                $posts_array = get_posts( $args ); 

            ?> 
            <div id="news">
                <div id="news-roll" class="mcenter">
                    <h3><?php _e('Siste nytt:', 'monster'); ?></h3> 
                    <?php 
                    $count = 1;
                    foreach ($posts_array as $monster_news) { 
                        setup_postdata($monster_news);

                        if ($count == 1) {
                            echo '<p class="first-news">'; 
                        } else {
                        echo '<p>';
                        }

                        the_title();

                        echo '</p>';

                     } 
                     $count = null;
                     ?>
                </div>
            </div>

Change:

foreach ($posts_array as $monster_news) { 
                    setup_postdata($monster_news);

To:

foreach ($posts_array as $post) { 
                    setup_postdata($post);

It seems setup_postdata() actually doesn't modify $post itself (which was news to me).

PS also loose empty , in array... I am not sure how it actually works for you with that.
