For the life of me I am unable to get these twitter bootstrap buttons to text wrap onto multiple lines, they appearing like so.

I cannot post images, so this is what it is doing...

[This is the bu] tton text

I would like it to appear like

[This is the ]

[button text ]

<div class="col-lg-3"> <!-- FIRST COL -->
  <div class="panel panel-default">
    <div class="panel-body"> 
    <h4>Posted on</h4>
    <p>22nd September 2013</p>
    <h4>Tags</h4>
    <a href="#" class="btn btn-primary btn-xs col-lg-12" style="margin-bottom:4px;">Lorem ipsum dolor sit amet, consectetur adipiscing elit.</a>
   <a href="#" class="btn btn-primary btn-xs col-lg-12" style="margin-bottom:4px;">Lorem ipsum dolor sit amet, consectetur adipiscing elit.</a>
   <a href="#" class="btn btn-primary btn-xs col-lg-12" style="margin-bottom:4px;">Lorem ipsum dolor sit amet, consectetur adipiscing elit.</a>
           </div>
  </div>
</div>

Any help would be much appreciated.

Edit. I have tried adding word-wrap:break-word; but it is not making any difference.

Edit. JSFiddle http://jsfiddle.net/TTKtb/ - You will need it expand the right column so the panels sit next to one another.
