Mega-Blonde Jessica Simpson shocked everyone when she danced into LA club Hyde as a brand-new bottle redhead - then reappeared re-dyed at Hyde just four days later...this time as a brunette! But as Jessica stood giggling with galpals about getting back to her roots, a feisty female suddenly came out of nowhere, went in her face and snarled: "A leopard can't change her spots - you're a dumb blonde and you ALWAYS will be!" Jessica burst into boo-hoo's, ran into the ladies' john - then exited the joint moments later.
