It would have sounded better if the title of this post was actually Helena Christensen Nude for Nike, but she actually got naked for a Reebok ad, so no alliteration today. Still, it completely doesn't matter what company is paying Helena Christensen to get naked, as long as she's getting naked. I assume the message here is that if you buy Reebok shoes, you'll look as hot as a naked Supermodel. Either that or you'll run faster if you're naked. I prefer the latter.
