I've been watching the tape of Britney Spears' performance at that NFL concert until my wrist hurts, and I've come to one inescapable, disturbing conclusion: She's developing some seriously chunky thighs.
Now don't get me wrong.... I definitely wouldn't kick her out of my living room if she came by and, um, "personally sang" for me, but it's definitely time for her to switch to the Diet Pepsi Vanilla.
