Heidi Klum - 12th Annual Halloween Party in Las Vegas October 29, 2011

Project Runway host and supermodel Heidi Klum brought her legendary Halloween party, in its 12th year, to Tao at the Venetian last night for the first time.

The Queen of Halloween fueled up for the night with Tao favorites in her room as she morphed into her costume with makeup by Bill Corso. Klum donned her eye-catching “Visible Woman” costume, a bodysuit painted with muscles, veins and tendons that make up the human body (think Bodies: The Exhibit, currently at the Luxor) and arrived on the red carpet on a gurney carried by bloody medics.

Fans lined the escalators up to Tao to catch a glimpse of the “either you’re in, or you’re out” hostess who this week crowned Anya Ayoung-Chee the winner of Season 9 of Project Runway. In the nightclub, Klum took over VIP tables on the dance floor with a group that included The Real Housewives of New York star Bethenny Frankel and her husband Jason Hoppy.

Klum, who is the 2011 Trick-or-Treat for UNICEF ambassador, was surprised with tricks and treats throughout the night as her favorite DJ ?uestlove spinned. Klum was presented with an intricately carved pumpkin by carver Ray Villafane, and a bloody version of Tao’s bottle fairy flew over the dance floor hanging by a noose. Klum, without singer husband Seal, danced and partied until nearly 4 am.
