Heidi Klum is many things — model, Project Runway host, former muse to Seal — but she is foremost an extremely committed Halloween party host. This year she threw her 20th annual spooky season bash, once more spending hours of time and presumably thousands of dollars at the prosthetic studio to create a freaky Frankenstein's alien look.
None of her many famous guests could compete, but most of them (Owen Wilson, WYD?) at least tried. Mariah Carey was a surprisingly convincing hair metal musician, Neil Patrick Harris was a paparazzi-shy Olsen twin, Antoni Porowski was a zombie Blockbuster employee. As is the current trend, many celebs dressed as other celebs, but there were plenty of classic standbys too, from Holly Golightly to the Phantom of the Opera.
