No one does Halloween like Heidi Klum. The supermodel is one of the holiday’s biggest celebrity enthusiasts, and each year she ups the ante for creativity at her annual party. While most stars are content to recreate memes or dress as sexy Disney characters, Klum pulls out all the stops with special effects makeup, latex, and a unique level of commitment. Over the years, her dedication has resulted in some truly memorable moments: Who can forget her anatomically correct 2011 transformation into one of the figures from Bodies: The Exhibition, or the painstaking detail of 2013’s elderly version of herself? Even her cuter costumes—last year’s Shrek and Fiona with her husband, Tom Kaulitz, for example—require hours in the makeup chair and months of preparation.

Naturally, Klum is planning something equally big for 2019—and if her Instagram posts are any indication, it’s going to be over-the-top scary. Currently getting ready in the window of Amazon Books on 34th Street, Klum is already drawing a crowd thanks to the ongoing steps of her metamorphosis. Joined by her full glam squad and a team from Amazon Prime Video, she began the process hours ago, moving from simple tweaks, like having her hair pinned down, to being helped into an intricate latex jumpsuit.

Though she’s documented the entire process on Instagram with photos and videos, no one can tell exactly what Klum will be dressed as—until, that is, she decides to make the big reveal. Given that she’s had plaster molds created for a special mask, and her jumpsuit cut open to reveal intestines, it’s safe to say that her look will be gory rather than glamorous. Still, Halloween’s reigning queen always finds a fresh way to surprise her audience: so watch this space.
