Heidi Klum’s annual Halloween bash consistently delivers unparalleled spectacle. In 2025, the supermodel, affectionately known as the “Queen of Halloween,” once again transformed into an unforgettable, grotesque creation for her 24th “Heidiween” celebration. Held at the opulent Hard Rock Hotel New York’s The Venue on Music Row, this highly anticipated event solidified its status as a cornerstone of the spooky season. As always, Klum’s own meticulously crafted costume set the bar, but her star-studded guest list also brought a dazzling array of imaginative, horrifying, and sometimes controversial ensembles to the red carpet.
Heidi Klum’s Monstrous Medusa: A Masterpiece of Transformation
For 2025, Heidi Klum unveiled a truly “ugly” and “scary” Medusa costume, a vision she had long dreamt of executing. This elaborate transformation featured a striking green, scaled bodysuit that extended into a long, snaking tail. Her headpiece was adorned with multiple moving snakes, complete with realistic fangs and a forked tongue, emphasizing the mythological Gorgon’s terrifying essence. Klum committed fully to the character, extending a vile tongue at photographers, a signature move that amplified her grotesque commitment.
Achieving this level of intricate detail required an immense collaborative effort. Klum worked with Oscar-nominated and Emmy-winning prosthetic makeup artist Mike Marino and a dedicated team of over 35 people. The preparation process alone spanned approximately 10 hours, showcasing the extraordinary dedication behind her annual reveal. Ahead of the party, Klum teased her followers with social media snippets and hinted on Good Morning America that her costume would be “very ugly” and “very scary.” She later confirmed, “I feel like we nailed it — to the teeth.”
Complementing Klum’s horrifying Medusa, her husband, Tom Kaulitz, perfectly embodied a man tragically turned to stone. Posing with a raised weapon and shield, he appeared frozen mid-battle, a direct victim of Medusa’s petrifying gaze. This coordinated effort further enhanced the theatricality and storytelling of Klum’s chosen theme, proving once again why she reigns supreme during the Halloween season.
The Genesis of “Heidiween”: A Two-Decade Legacy
Heidi Klum’s iconic Halloween party began nearly 25 years ago out of a simple desire. Finding a lack of suitable Halloween events in New York City, she decided to “take that one over.” Since then, her commitment to the holiday has only grown, fueled by the immense pressure to consistently outdo her previous costumes. Klum openly admits to experiencing “sleepless nights” ensuring her elaborate visions come to life. Her past transformations, including an 8-foot-tall Transformer, Michael Jackson’s werewolf from Thriller, a slithering worm, E.T., and Princess Fiona, demonstrate her unwavering dedication to creative excellence. Each year, Klum’s unique blend of artistry, ambition, and sheer willpower ensures “Heidiween” remains the most anticipated celebrity Halloween event globally.
