Heidi Klum [1] pulled out all the stops for her annual Halloween [2] bash in NYC on Monday night. As usual, the event brought out a bevy of stars including Gabrielle Union [3], Ice T and Coco, and Jackie Cruz. After months of anticipation, Heidi finally revealed her highly anticipated costume, which just so happened to be herself with five doppelgängers [4]. Heidi gave fans a sneak peek at her costume earlier in the day, sharing photos of prosthetics [5], a blond wig, and nude nails.
