Jessica Simpson reportedly melted down during her latest concert, forgetting the words to at least one song and stopping completely during another. According to a witness, she told the Grand Rapids crowd that it was difficult to feel so "vulnerable" and that she felt like walking off the stage.

News of this unfortunate performance gives credence to the theory that, like Samson with his glorious strength-giving mane, all of Simpson's diva power resides in those unflattering high-waisted pants.

That, or maybe the crowd was wearing Tony Romo masks? (Perez Hilton)
