Navigation displays different in IE7

[Danny M]

Hey,

The navigation for "next" and "previous" pages on my website show perfectly in Firefox, Chrome, Safari, IE8+ etc, but in IE7, they display a line underneath. Let me show you what I mean:

This is my website: http://www.lilwaynehq.com/2011/05/18/1-etranjj-i-own-it-feat-lil-wayne/

But in IE7, look at the navigation:

Does anyone know how I can fix that, so it will look like this:

I am using a specific style sheet for IE7 too.

Thanks in advance :)
