On Thursday, the model shared a video on Instagram, in which she stands still in underwear and high heels while a technician captured her on a recording device.

This Halloween will be a big one for Klum, who will be holding her 20th annual Halloween bash, and her costume is shaping up to be her most extravagant yet.
