Heidi Klum stuns as Medusa at her 2025 “Heidiween” party — You won’t believe the details behind the monster makeover

For more than two decades, Heidi Klum has reigned as the undisputed queen of Halloween — and this year, she has once again left fans speechless. The supermodel and television host transformed into the mythical serpent-haired Medusa for her 2025 Halloween bash in New York City, turning the night into a breathtaking blend of fashion, artistry, and spine-chilling creativity.

The 52-year-old star, famed for hosting Project Runway and her extravagant annual “Heidiween” parties, made a grand entrance at the Hard Rock Hotel dressed head-to-toe as the legendary Greek Gorgon known for turning her victims to stone. Every inch of Klum’s costume radiated craftsmanship and imagination — from the animatronic snakes slithering atop her head to the scaly bodysuit that wrapped her in serpentine detail.

Her husband, German rock musician Tom Kaulitz of Tokio Hotel, completed the cinematic transformation by appearing as a warrior frozen in stone — the ultimate victim of Medusa’s piercing gaze. The couple’s creative synergy once again stole the spotlight, embodying the essence of Halloween storytelling and performance art.

Behind Klum’s Medusa metamorphosis was Mike Marino, a celebrated Hollywood prosthetics designer who has worked with her on several previous Halloween masterpieces. Marino revealed that the inspiration for this year’s design came from Ray Harryhausen’s stop-motion Medusa in the 1981 classic Clash of the Titans. The result was an awe-inspiring, modern-day reimagining that combined special effects, mythological symbolism, and Klum’s flair for the dramatic.

According to Marino, the transformation required several dozen experts to bring the illusion to life. Klum’s costume incorporated a full snake suit with a built-in battery pack that powered the animatronic snakes and wheels that helped her glide across the blue carpet. The model’s glowing reptilian eyes and razor-sharp acrylic teeth heightened the eerie effect, making her nearly unrecognizable.

“It took months of preparation,” Klum admitted during interviews before the event. “I’ve been playing with the idea of Medusa for years — this time, I just wanted to do it right.”

True to form, her party drew an impressive lineup of celebrities, each vying for their own share of Halloween glory. Rapper Ice-T and his wife Coco Austin made a blood-curdling appearance, with Ice-T dressed in a red bodysuit wielding a fake cleaver while Coco went as a twisted version of the Chucky doll. Actor Darren Criss and his wife, Mia Swier, stole hearts as Shrek and Puss in Boots, while X-Men actress Famke Janssen channeled the cabaret icon Sally Bowles in a vintage-inspired ensemble.

Love Island USA star Amaya Espinal earned applause for her dazzling blue Na’vi costume, inspired by James Cameron’s Avatar. Even Chicken Shop Date creator Amelia Dimoldenberg joined the fun, dressing up as a cheeky tribute to Lily Allen and David Harbour’s high-profile split — a blend of humor and pop-culture commentary.

Klum’s Halloween legacy remains unmatched. Over the years, she’s appeared as an ogre, an alien, an elderly version of herself, and even a full-body worm. Each year’s transformation pushes the limits of costume design, turning Halloween into a stage for high-concept art.

While Medusa might be one of her most ambitious looks yet, Klum hinted she’s already planning for 2026. “Inspiration hits me suddenly,” she said with a grin. “Sometimes I just know — this is the one.”

For fans of fright and fashion alike, Heidi Klum’s Halloween spectacle is more than a costume party — it’s a cultural event where myth, makeup, and mastery merge under the glow of New York’s spooky skyline.
