Heidi Klum Teases Gory Halloween Costume with Bloody Prosthetics

Heidi Klum is once again pushing the limits of Halloween glamour with her 2026 costume, which appears to be a nightmarish fusion of human anatomy and underwater life. The supermodel, 53, shared a close-up Instagram image of her upcoming look, revealing textured, flesh-like prosthetics in vivid colors that resemble organs—some likened to brains or intestines ^[1]. The image, posted on October 24, has fans speculating wildly, with guesses ranging from the coral reef of St. Barts to a Clicker from The Last of Us or even a reference to the body horror film The Substance, according to fans ^[3].

Klum, known for her elaborate annual Halloween party—dubbed ‘Heidiween’—has not revealed the full costume yet. However, she did hint at its theme in a September interview with Parade, saying it would be ‘bloody’ and that it ‘goes very well with red wine’ ^[3]. She also noted that blood transfusion bags and gory imagery are central to her Halloween inspiration ^[2].

Last year, Klum transformed into Medusa, complete with green scales, animatronic snakes in her hair, and a rattlesnake tail—her husband Tom Kaulitz dressed as a stone soldier to match ^[2]. Previous costumes have included a giant earthworm, an alien with purple hair and stilts, and a skinless human body, cementing her status as a Halloween legend ^[3].

This year’s look continues her tradition of extreme commitment, with fans already calling it ‘gagging’ and ‘not advised for the squeamish’ ^[3]. The costume is reportedly being crafted with hand-painted prosthetics, and Klum was recently seen browsing a fabric store for materials, confirming her hands-on approach ^[2].

The annual event, now in its 24th year, is held in New York City and draws celebrities, performers, and fans from around the world ^[3]. With only a week left until the party, speculation is building over whether the costume will be a literal organ garden, a sea creature, or a twisted homage to horror cinema.
