Heidi Klum has shared a final series of clues about her Halloween costume as she prepares to host her annual celebrity party in New York City. The 53-year-old supermodel posted images of unusual prosthetics, including a mouth-like structure with distorted teeth, ahead of the October 31 celebration. She has also confirmed that her costume will feature blood-inspired effects and require an elaborate physical transformation.
The German model and television personality has kept the identity of her costume secret despite releasing several previews throughout the week. Her 25th annual Halloween party is scheduled for Saturday night, with the full costume expected to be revealed during the event.

Klum posted her first major costume clue on October 24, showing a close-up photograph of colourful prosthetic materials.
The image featured unusual shapes and textures resembling internal organs, coral and other organic structures.
She captioned the Instagram post, “What’s my costume?” and added, “One week to go….#HeidiHalloween.”
Further previews followed during the week, including photographs of flesh-coloured materials and a structure resembling a body mould.
On October 30, Klum shared another teaser featuring distorted teeth and mouth-like details.
She wrote, “Your final clue…. See you TOMORROW 😛👻”
The posts prompted speculation about the character she intends to portray, although Klum has not officially identified her costume.
What Will Heidi Klum Wear for Halloween?
Klum has confirmed that her Halloween costume will have a horror-inspired appearance.
During a September interview, she described the planned outfit as “very, very bloody.”
She also explained that the costume would complement a red wine theme associated with her Halloween collaboration.
At a pre-party event on October 29, Klum provided another detail about the physical design.
“My body is going to fit in a shape that normally a human body would not fit in,” she said.
The statement suggests that the costume will involve a substantial change to her body shape rather than conventional clothing and makeup.
However, the exact character remains unconfirmed.

Klum’s unusual prosthetic previews have generated several theories about her planned transformation.
Some social media users believe the costume could represent Monstro Elisasue, the creature featured in the 2024 body-horror film The Substance.
Others have suggested a Clicker from The Last of Us or Vecna from Stranger Things.
Additional guesses include characters from Resident Evil and underwater creatures.
The theories are based on the appearance of the materials shown in Klum’s photographs and videos.
Neither Klum nor her costume team has confirmed any of these suggestions.
