jquery tabs function on click

Only problem that i have is when page load, all 4(four) tabs have .current class on it. Want i want is that 1st tab (data-tab="tab-1) have class .current on page load and all other to be hidden. Here is my full project section

$('ul.tabs li').click(function(){
        var tab_id = $(this).attr('data-tab');

        $('ul.tabs li').removeClass('current');
        $('.tab-content').removeClass('current');

        $(this).addClass('current');
        $("#"+tab_id).addClass('current');
    });

.tabs li.current {
  color: red;
}
.tab-content {
  display: none;
 }
.tab-content.current {
  display: block;
}
