simultaneous fadeOut() and slideUp()

simultaneous fadeOut() and slideUp()

I am trying to develop a function to simultaneously fade elements out and slide them up. The following attempt doesn't work. It applies the animations sequentially. How can I fix it?

/******************************************************************************
  .slideFadeOut()
******************************************************************************/
(function($) {
  $.fn.slideFadeOut = function() {
    this.
      queue('fx2', function() {
        $(this).slideUp({duration: 2000});
      }).
      dequeue('fx2');
    this.
      queue('fx3', function() {
        $(this).fadeOut({duration: 2000});
      }).
      dequeue('fx3');
    return this;
  };
})(jQuery);
