Heidi Klum once again took Halloween to a whole new level at her legendary annual celebration in New York City. Hosting her 25th "Heidiween" party, the supermodel stunned guests on Saturday by transforming herself into a giant, bloody severed hand!

The elaborate costume featured a gruesome wrist, with Heidi's head positioned right in the center of the hand. Every detail was carefully recreated, including a green wedding ring and the "Tom" tattoo on one finger—a sweet tribute to her husband, Tom Kaulitz.

And her grand entrance was just as spectacular! Heidi arrived in a truck covered with red "DANGER" signs before being escorted out by assistants dressed in yellow protective suits, making the whole scene look like something straight out of a horror movie.

Heidi Klum's Second Costume Featured Giant Fingers as Boots!

But the Halloween queen had another surprise waiting for her guests! After her red-carpet appearance, Heidi removed the enormous hand costume to reveal an equally creepy second look underneath.

She wore a blood-splattered, flesh-toned bodysuit paired with a gruesome face mask and a long, platinum-blonde wig with bangs.

The most unexpected detail? She kept two fingers from her original costume, transforming them into bizarre over-the-knee boots complete with long, bright-red nails!

The unusual footwear perfectly tied both looks together, proving once again that when it comes to Halloween, Heidi Klum never does anything halfway.

Heidi Klum Teased Her Bloody Halloween Transformation Before the Big Reveal

Even before the big night, Heidi Klum (53) had been dropping clues about her terrifying Halloween transformation. In the days leading up to the party, the supermodel shared several behind-the-scenes glimpses on Instagram, teasing fans with close-ups of gruesome prosthetics, decaying organs, rotting skin, and other disturbing details.

On Thursday, she revealed another intriguing clue: a mannequin made to her exact measurements, complete with a disassembled hiking backpack attached to its back.

Heidi had also hinted at just how bloody her costume would be. "It goes very well with red wine. It's very, very bloody," she told 'People.'

With those cryptic teasers, it was clear that the Halloween queen was preparing another spectacular—and particularly gruesome—transformation for 2026.

Why Was Tom Kaulitz Missing From Heidi Klum's Halloween Party?

One familiar face was noticeably absent from this year's celebration: Heidi's husband, Tom Kaulitz.

In previous years, the musician had frequently joined his wife in elaborate, coordinated costumes. In 2025, for example, Heidi transformed into a terrifying, hissing Medusa, while Tom complemented her look as a stone soldier.

Over the years, Heidi has become famous for her extraordinary Halloween creations, transforming herself into everything from Jessica Rabbit and an elderly version of herself to a giant worm.

And with this year's bloody severed-hand costume, she once again proved why she's considered the ultimate queen of Halloween!
