Heidi Klum is getting into the Halloween spirit one week early with a sneak peek at her latest costume.

The model shared a photo of a frightening prosthetic on Instagram.

Fans are already sharing their guesses about what Klum has in store for her yearly Halloween bash.

Halloween is one week away, and Heidi Klum is already terrorizing the masses with her latest costume.

The supermodel, known for going above and beyond with her elaborate (and often horrifying) costume creations, has unveiled a sneak peek at this year’s outfit. The image is, unsurprisingly, textured, strange, and deeply confusing.

“What’s my costume?” Klum captioned an Oct. 24 Instagram post, adding a series of spooky Halloween emojis. “One week to go….#HeidiHalloween.”

The photo itself is a close-up of a colorful prosthetic, which shows several different shapes and colors molded together in a design that resembles a coral reef just as much as it resembles human organs and mushrooms. Needless to say, fans are struggling to figure out what exactly Klum has in store for All Hallow’s Eve.

“Coral reef. Inspired by St Barth’s,” one user guessed, referencing the restoration efforts in the Caribbean.

“The mushroom zombie from The Last of Us,” posited another. Several commenters backed this guess, pointing specifically to the Clicker zombie design in the HBO adaptation of the hit Naughty Dog game.

“Looks like organs,” one fan remarked, with another user noting, “They look like internal organs that were torn into halves.”

Other guesses had commenters point to The Substance, The Little Mermaid’s Ursula, SpongeBob, and the Demogorgons from Stranger Things. Alas, only time — or Klum herself — will reveal the truth.

Klum has offered very few hints about her costume in the past few weeks, but did promise Parade in September that it would be “bloody.” She has otherwise been pretty tight-lipped, but told the outlet that she is particularly proud of the costumes in which she appears utterly unrecognizable.

“I loved when I made myself really old,” she said. “That’s a lot of fun. I turned myself into someone who was like 90. I also loved being an alien. I was really kind of a robot alien. I was red with purple hair, and I was on stilts, so I was like extra tall.”

Last year, Klum pulled out all the stops for her transformation into Medusa. The model called upon a team of stylists to turn her into the creepy and scaly figure of Greek myth. In the lead-up to Halloween night, she detailed the process, giving fans time to guess at her costume: the heavily wrinkled green prosthetics, green contacts, and frightening fangs eventually made sense when it all came together to show Klum’s Medusa in her final form.

Prior years have seen Klum embody everything from Shrek’s Fiona and Steven Spielberg’s E.T. to a giant worm. Though the latter may sound simple, the costume became a subject of social media fascination in all of its strangeness.

Like in years prior, Klum’s 2026 costume will be revealed to the world when the model steps out for her annual Halloween bash in New York City, a tradition she began in 2000. Naturally, costumes are required for the invitation-only event.
