Heidi Klum—who for more than two decades has turned Halloween into a high-glam spectacle—has once again dialed up the anticipation. In the lead-up to her 2025 annual Halloween party, she revealed that her costume will be intentionally “very ugly and super scary”, a stark shift from last year’s “cute” E.T. look.

A Promise of Bad-Beauty
On the show The Tonight Show Starring Jimmy Fallon, Klum disclosed that planning started “months ago” and that this year she wanted to go in the opposite direction of glam: “I’m going to be very ugly because I always try to do something different,” she said.
Her tease included vague clues—a plaster prosthetic, metal constructions, and the name of pro MAKE-UP artist Mike Marino suggesting the transformation will be heavy-duty.
The Reveal: Mythical Monster Mode
When the night finally came, Klum arrived at her 24th annual Halloween bash dressed as Medusa—covered in green body paint, adorned with sculpted, moving snake-like hair and metallic fangs. Her husband, Tom Kaulitz, complemented the look by appearing as a man transformed into stone, nodding to the legend’s myth. The full transformation reportedly took around ten hours to apply.
Statement Costume, Statement Event
Klum’s annual party isn’t just a guest-list bash—it’s become a fashion moment, meme generator and social-media event rolled into one. Her declaration of “ugly” was less about sloppy and more about subverting beauty: turning it monstrous, sculptural, unforgettable. By promising ugliness, she made the look itself a topic of conversation ahead of the reveal.

Why This Matters
This year’s costume shows how Halloween has evolved into a major branding and cultural moment for celebrities. When a figure like Klum teases “ugly” rather than “glam”, it flips expectations—making horror high fashion, and turning the costume into a campaign rather than just dress-up. For fans and media, the buildup and reveal become as important as the outfit itself.
With her Medusa transformation and months-long build-up, Heidi Klum has again raised the bar for celebrity Halloween theatrics. Her annual party remains a master class in spectacle, style and social-media savvy—proving that in 2025, the biggest costume is the one you can’t stop talking about.
