Heidi Klum is preparing to surprise Halloween fans with what could be one of her most terrifying costumes yet.
With just seven days remaining before her famous celebrity-filled Halloween party, the supermodel has offered a sneak peek at her mysterious 2026 look, hinting at an elaborate transformation that could leave fans stunned.
Heidi Klum Shares First Look at Her Halloween Costume
On October 24, Klum took to Instagram to share a preview of her upcoming costume, captioning the post, “What’s my costume?” followed by Halloween-themed emojis. She added, “One week to go….#HeidiHalloween.”

Fans Speculate About Her Mysterious Transformation
Klum has built a reputation for her imaginative Halloween costumes, drawing inspiration from pop culture, horror films, and the natural world. Her previous transformations have included Fiona from Shrek, a giant earthworm, and the mythological figure Medusa.
Unsurprisingly, her latest Instagram post sparked plenty of theories about what she might be planning for this year.

There were also guesses that the costume could have an underwater theme. Several followers imagined Klum appearing as the Great Barrier Reef or another ocean-inspired creation.
The Supermodel Promises a Bloody Halloween
While fans will have to wait until October 31 to see the complete costume, Klum has already revealed that horror will play a major role in her plans.
In an interview with People published on September 17, the 53-year-old teased that her outfit would be “very, very bloody.”
“That’s what Halloween is all about,” she said. “We go gory, and we go there.”

Looking Back at Klum’s Elaborate Medusa Costume
Klum delivered another memorable Halloween moment last year when she transformed into Medusa. Her striking green ensemble featured robotic snakes attached to her head, and creating the intricate costume reportedly took around 10 hours.
Her husband, Tom Kaulitz, completed the theme by dressing as a warrior or a man turned to stone, complementing the mythological inspiration behind her appearance.
Speaking to E! News at the 2025 Halloween party, Klum praised the team responsible for bringing her costume to life.
“Everything is hand-painted,” she explained, adding that approximately 15 people had worked on the project. She also expressed her satisfaction with the finished result, saying she believed the team had done a fantastic job.
With another Halloween celebration approaching, Klum's latest teaser has once again left fans wondering what kind of extraordinary creation she will unveil on the red carpet.
