Heidi Klum Teases Elaborate Halloween Costume Ahead of Annual Party

Supermodel Heidi Klum is preparing to unveil another elaborate Halloween transformation, sharing a fresh teaser on Instagram on October 27, 2026, ahead of her annual costume party in New York City. Her latest preview features a mysterious, bloody concept that has prompted fans to speculate about the character she will portray.

Klum's 25th annual Halloween party is scheduled for October 31. The model, widely recognized for her elaborate and often grotesque costumes, has revealed only limited details about this year's creation, including an image of unusual, organ-like prosthetics posted on October 24.

In her October 27 Instagram post, Klum wrote, "4 more days," alongside spooky emojis and the hashtag #HeidiHalloween.

Mike Marino, the special effects makeup artist who has collaborated with Klum for years, offered another glimpse of the production during an interview with NBC's Hollywood ReelTime. He described the project as exceptionally demanding.

"one of the most elaborate costumes ever made," Marino said, describing Klum's look this year.

Marino emphasized the technical challenges involved in creating the costume, noting that the work behind such transformations may not always be apparent to viewers.

"It's so difficult to do and just the complication of it is really challenging," Marino said.

He also explained that the complexity of these creations can be underestimated despite the extensive effort required to produce them.

"It might not appear to some people sometimes how much work goes into it but there's so much that goes into these things," Marino said.

The latest teaser has generated numerous theories among Klum's followers. Suggestions have included internal organs, the sea creatures from Pirates of the Caribbean associated with the Flying Dutchman, Monstro Elisasue from The Substance, Ursula from The Little Mermaid, a Clicker from The Last of Us and a monster from Resident Evil.

Some commenters focused on the apparent anatomical details in the image, while others proposed characters from fantasy and horror franchises. Klum has not confirmed any of the suggested identities.

In an interview with Parade, Klum offered one additional description of the costume, saying it would be "bloody." She has not disclosed further details about the final design.

Klum's previous Halloween transformations have included E.T., a giant peacock, a worm, a zombie-like creature and Fiona from Shrek. At her 2025 Halloween party, she appeared as Medusa, wearing a scaled body and a tail, with a headpiece featuring snakes.

Her husband, Tom Kaulitz, has also participated in past costume concepts, including appearing as the Greek soldier turned to stone by Medusa, a bloodied fisherman and Shrek alongside Klum's Fiona.

Klum told Parade that her annual Halloween celebration began after she attended parties where she felt the costumes lacked effort. She hosted her first Halloween party in 2000 and has continued the tradition with increasingly elaborate themed appearances.

"I'd go to some of these Halloween parties and people were just not given anything," Klum told Parade.

She explained that her dissatisfaction with the parties and costumes she encountered helped inspire her to organize her own event.

"This is really how it sparked my idea on doing one myself because I thought all the parties were so lame and the costumes people were doing even lamer," Klum told Parade.

She added that she wanted to encourage guests to approach Halloween costumes with greater creativity.

"There needs to be a person who really shows them to give more," Klum said.

Klum's next scheduled appearance in her 2026 Halloween costume is at her annual party on October 31 in New York City.
