Don’t look directly at Heidi Klum’s 2025 Halloween costume.

The 52-year-old supermodel’s love of Halloween is as legendary as her elaborate costumes, which she reveals each year at her star-studded Halloween bash in New York City.

This year, Klum again was unrecognizable as she transformed into Medusa, a figure from Greek myth who has snakes instead of hair. She’s known for being so hideous that anyone who sees her turns to stone.

For the costume, Heidi had a prosthetic forked tongue and fake snakes moving on her head. Her face and body was covered with scales, and she wore bright green contact lenses.

“HAPPY HEIDIWEEN 🐍Don’t stare too long or you’ll turn to stone 🖤 #HeidiHalloween,” she captioned the reveal on Instagram.

On the red carpet, husband Tom Kaulitz accompanied her as one of Medusa’s victims: a stone figure.

Keeping with tradition, Klum was tight-lipped about her costume until the big reveal, though she told People this week that it won’t be pretty.

“I’m going to be very ugly because I always try to do something different,” she said. “I thought last year, I was very cute with my husband as E.T. And the year before that, we were the big peacock with performers.”

Klum’s joint peacock costume with her husband, musician Tom Kaulitz, required 15 additional people to navigate. She felt the need to create that more “complicated” costume, she told People, because her creepy worm costume in 2022 “felt so simple.”

Klum added that she strived this year to do “something new again.”

On Oct.31, Klum began dropping hints about her costume early in the day on Instagram, first sharing a close-up pic of her terrifying fangs. “Ok ….. here we go,” she captioned it, adding ghost and spider emoji.

Over the course of the day, she continued teasing fans by showing images of herself having pea-green makeup applied to her face.

By evening, Klum shared a video of a makeup artist applying a latex-like material to her face that resembled monstrous flesh. She followed that up with a close-up video of her mouth as more fake green flesh was applied to her face.

Klum also shared a video of her and Kaulitz on her Instagram story that showed the guitarist’s normally dark mustache and beard flecked with white.

Last year, Klum arrived at her annual Halloween party dressed as E.T., the lovable alien from Steven Spielberg’s hit 1982 sci-fi flick “E.T. the Extra-Terrestrial.”

Her costume was inspired by the makeover E.T. gets from his young friend Gertie, played by Drew Barrymore, who was just 7 when “E.T.” was released. As in the movie, Klum’s E.T. sported a long blond wig, red lipstick and a black hat and scarf.

Kaulitz accompanied Klum to the party dressed as E.T. without the wig, lipstick and human clothes.

Klum shared a behind-the-scenes video this week on Instagram that showed her and Kaulitz working with costume designers last year to create their E.T. looks.

“I have sleepless nights over Halloween. You have no idea,” Klum says in a voiceover at the video’s onset. “I always hope that it works out.”

The video then shows Klum walking down a hall to meet Kaulitz and the costume designers. “This is Halloween, this is Halloween, this is Halloween!” she excitedly chants.
