Anatomy 101 with Heidi Klum!
The Halloween-loving supermodel and "Project Runway" host, 38, managed to top herself yet again at her eponymous Halloween Party held Saturday at Tao at The Venetian in Las Vegas.
Klum revealed more than she ever has before, sorta, as a female anatomical figure -- wearing a bloody skintight getup with painstaking details.
And the married mom of four, wearing platform heels, entered the red carpet appropriately -- passed out on a stretcher, escorted by two bloodstained doctors!
The beauty, whose Halloween parties have become legendary -- as have her over-the-top costumes -- will don another costume on Monday night for her second bash, this one at NYC's PH-D at the Dream Downtown.
Us Weekly had the first sneak peek of Klum putting the final touches on that getup, in which the former Victoria's Secret catwalker will channel her inner ape with monkey ears, a hairy bodysuit and fangs.
