Wet hair, don't care

Now that we're all up to speed on why celebrities — from Justin Timberlake to Emmy Rossum — are pouring a bucket of ice water over themselves, it appears the most powerful face in fashion is also taking part in the cause to benefit The ALS Association.

Watch the sneak-peek clip below, and then see how it all goes down on Vogue's Facebook page and find out who she challenges.
