Heidi Klum Unveils Her 2025 Halloween Look as a Mythical Creature Alongside Tom Kaulitz

The queen of Halloween outdid herself once again, arriving in a transformation that left fans both amazed and unsettled by its intricate, lifelike design.

Heidi Klum once again proved why she reigns supreme as Halloween's ultimate showstopper. On October 31, 2025, she attended her annual Hallowe'en Party in New York, transforming into an otherworldly mythical creature that turned heads and dominated social media.

Covered head to tail in a textured suit of green and gold scales, Klum embodied a serpentine figure with incredible precision. Her face was unrecognizable beneath layers of prosthetics that gave her reptilian skin, fanged teeth, and piercing, glowing eyes.

Coiled snakes — some animatronic — sprouted from her head, their lifelike movements creating an eerie illusion that captivated everyone watching.

Her clawed hands and elongated tail completed the transformation, which curved dramatically across the blue carpet as she struck fierce, snake-like poses for photographers.

Every detail, from the sculpted ridges on her torso to the flicking forked tongue, underscored the craftsmanship and imagination behind the look.

Another person shared, "The moving snakes!!!!!" A fourth typed, "This costume looks very realistic! 😳 Whats that in her mouth?? A rodent?👀 [sic]" Another joked, "I bet the tongue was uncomfortable for a bit."

Others were simply stunned, with one calling the look "Insane." Another netizen summed up the mood perfectly, posting, "Omg they're moving! Ahhh she wins [sic]." Another fan echoed the sentiment with, "Wow. I think this is probably her best." "She outdid herself this year!" another netizen commented.

More praised the model's creative direction, with one person noting, "I absolutely love that she went with Medusa's true form instead of just the hair and makeup. Thank you."

A different viewer admitted, "That's actually terrifying the way the snakes are moving 🫣 in other words, excellent costume Heidi ☺️." Another added, "The best 🐛 🔥 Iconic🔥."

On the carpet, Klum was also joined by her husband, Tom Kaulitz, who complemented her look perfectly. He appeared as a stone warrior, his entire body painted in textured gray to resemble weathered marble.

Complete with a helmet, armor, and a large shield, his costume created the image of a petrified soldier frozen in battle — perhaps one of Medusa's unfortunate victims. Together, the pair turned the carpet into a mythological tableau, cementing their reputation as Halloween's most imaginative duo.

Ahead of her annual Halloween celebration, Klum gave fans a behind-the-scenes look at the intricate preparation that went into her transformation. On Instagram, she shared a series of clips that documented the lengthy process step by step.

In one video, Klum was seen seated in a makeup chair as her skin was carefully painted a vivid green, laying the foundation for the reptilian look.

Another clip showed prosthetic pieces being meticulously glued onto her face, gradually reshaping her features into those of the mythical creature.

She later posted a snapshot revealing a tangled web of mechanical wiring — the system responsible for animating the snakes woven into her headpiece.

Finally, Klum unveiled a short video of the completed transformation, emerging in full costume as the Medusa-like serpent creature. The post offered fans a rare glimpse into the hours of artistry, precision, and technical ingenuity that made her 2025 Halloween look one of her most ambitious creations to date.

However, Klum's 2025 transformation wasn't the first time she stunned fans with her creativity and commitment to detail. The supermodel has been redefining Halloween for decades, turning her annual celebration into one of the most anticipated events of the season.

Her approach has always been guided by one rule. "I always try to find things that people naturally wouldn't do. Most people do nurses or police officers, but I was always looking for something that I hadn't seen," she explained.

In 2024, Klum took that philosophy to another level with a costume that paid homage to one of film's most beloved extraterrestrial characters.

She arrived at her New York Halloween bash completely unrecognizable as E.T. in disguise — the version of the alien seen wearing a blonde wig, hat, and red shawl in the 1982 classic.

The attention to detail was remarkable. Her body was encased in layers of textured prosthetics that mimicked E.T.'s wrinkled skin, while her large blue eyes and glowing fingertip brought the character to life.

The whimsical look was both nostalgic and uncanny, managing to capture the innocence of the original character while still maintaining Klum's flair for realism. As she posed for photographers, her intricate transformation turned the carpet into a scene straight out of the movie.

From cinematic icons to mythical monsters, Heidi Klum's transformations continue to set the standard for creativity and dedication — proving that for her, Halloween isn't just a costume party, it's an art form.
