Getting the post_author from p2p_get_connection( $p2p_id )?

I am adding a Buddypress activity stream item every time a tweet is connected to a post, and I need to add this as an activity of the author of the tweet.

The following code works perfectly, but am I calling the related tweet author properly? It feels too roundabout a way to be doing this:

// Add a Buddpress activity to the Activity Stream every time a tweet_to_post connection is created
function handle_new_connection( $p2p_id ) {
	$connection = p2p_get_connection( $p2p_id );
	if ( 'tweets_to_posts' == $connection->p2p_type ) {

		global $wpdb;

		$ConnectedTweetID   = $connection->p2p_from;
		$TweetAuthorID      = $wpdb->get_var( $wpdb->prepare( "SELECT post_author FROM $wpdb->posts WHERE ID = %d", $ConnectedTweetID ) );
	    $PostTitle          = get_the_title($connection->p2p_to);
	    $PostPermalink      = get_permalink($connection->p2p_to);
	    $TweetTitle         = get_the_title($connection->p2p_from);
	    $TweetPermalink     = get_permalink($connection->p2p_from);
	    $TweetAuthor        = get_userdata($TweetAuthorID)->display_name;
	    $TweetAuthorSlug    = get_userdata($TweetAuthorID)->user_login;
	    $TweetAuthorLink    = get_author_posts_url($TweetAuthorID);

		bp_activity_add( array(
			'item_id' => $p2p_id,
			'user_id' => $TweetAuthorID,
			'component' => 'activity',
			'type' => 'tweet_connected',
			'action' => '<a href="' .$TweetAuthorLink. '">' .$TweetAuthor. '</a> posted <a href="' . $PostPermalink . '">'. $PostTitle . '</a>',
			'content' => '"<a href="' . $TweetPermalink . '">' . $TweetTitle . '</a>"',
	 ) );
  }
}
add_action( 'p2p_created_connection', 'handle_new_connection' );

Is there a better/more efficient way to do this?

Any help is much appreciated.
