Get all published language variants of a page

Hey all 

How do i get only a list of published langauges for a page (langauges that are available to front end user). 

var xxxxx = currentPage as ILocalizable;

xxxxx.ExistingLanguages 

Seems to return me all langauges even language's the page has only been created in although not published. 

currentPage.ExistingLanguages.Select(x => x.Name); is the same. 

Thanks
