Querying posts from current category, using a variable as array argument

Already figured it out and seems to be working just fine.

                  // set up or arguments for our custom query
                      $paged = ( get_query_var('paged') ) ? get_query_var('paged') : 1;
                      $category = single_cat_title('', false);
                      $query_args = array(
                        'post_type' => 'post',
                        'category_name' => $category,
                        'posts_per_page' => 3,
                        'paged' => $paged
                      );
