Our appetites whetted with the release of the upcoming Vanity Fair Hollywood Issue cover featuring ten of today's most desirable starlets in a variety of glamorously uncomfortable poses (sooo much better than last year's shoot featuring four overexposed comedians and some hotly buzzed penguins whose careers quickly nosedived), we delved deeper into VanityFair.com's stash of preview goodies. It was there that we discovered Renée Zellweger starring in the most amazing piece of video that we've seen in at least the last twelve hours.
