[TYPO3-ttnews] how to get alternative title through fluid

[Jaco Graaff]

In the Metadata tab of a news item there is a Alternative title field 
and speaking URL path segment

can I get the Alternative title field through fluid??

i.e:
I tried:

<span class="title">{newsItem.title}</span>
<!-- try to use the alternative title as well -->
  {newsItem.alternative}
{newsItem.alttitle}
{newsItem.alttitle}
{newsItem.alt}
{newsItem.alternativeTitles.title}
