How to add badge on top of Font Awesome symbol?

Question

I would like to add badge with some number (5, 10, 100) on top of the Font Awesome symbol (fa-envelope). For example:

But, I can not understand how to put the badge on top of the symbol. My attempt is available here: jsFiddle.

I would like to have it support Twitter Bootstrap 2.3.2.

This can be done with no additional mark-up, just a new class (which you would use anyway) and a pseudo element.
