RSS Feed Validation Error

So, apparently my RSS feed hasn’t been working for awhile and I can’t seem to find the issue that the feed validator says is the problem.

site: http://www.adorkableme.com
feed: http://www.adorkableme.com/feed/

This is the error that I’m getting from the validator:

This feed does not validate.

line 396, column 0: XML parsing error: <unknown>:396:0: junk after document element

I can’t find that ANYWHERE in my source or in the plugins.
This is the code: <style type="text/css">#sp, #sp a {font-size: 9px;color: #909090;border-bottom: none;clear: both;}</style><div id='sp' style='text-align:right;'></div>
I can find it when I view my source, I just don’t know where it’s pulling it from.
