Heidi Klum gives sneak peek at her latest epic Halloween costume

When it comes to Halloween costumes, nobody does it better than Heidi Klum. She’s been Betty Boop, Jessica Rabbit, a cadaver, the Garden of Eden’s snake and the apple that tempted Eve, Fiona from Shrek and even herself.

Now she’s letting fans get a sneak peek at her latest over-the-top creation, which she’ll reveal in full on the morning of Oct. 31 from the window of the Amazon store on 34th Street in New York City.

The German supermodel is once again bringing out the big guns, enlisting prosthetic makeup designer Mike Marino, who has worked on films like Black Swan and I Am Legend. In a video posted to Klum’s Instagram account on Wednesday, Marino can be seen sculpting a mysterious mold that’s bound to be all the rage come Halloween. But what is it?

Klum’s fans have some guesses. Given the figure’s curved headpiece, many have speculated that she’ll be suiting up as an alien — specifically a “Conehead” from Saturday Night Live fame. Marie Antoinette, Cleopatra and Lady Liberty have also been thrown out there, as has the spooky suggestion of Frankenstein’s Bride.

Whatever it is, it’s guaranteed to be jaw-dropping. At least, it had better be, given that Klum — who throws a star-studded Halloween bash each year — will be getting ready for 10 hours, according to her Instagram post. Give her all the king-size Snickers bars, folks.
