Heidi Klum gives sneak peek into her 2025 Halloween look

Heidi Klum is gearing up to unleash her most terrifying Halloween costume yet, and fans are already speculating about the gruesome transformation. 

The Project Runway alum teased her latest look on Instagram, sharing a close-up of her face covered in green makeup, with matching eyebrows and a bald cap.

"This is only the beginning," Klum captioned an earlier post, showcasing a realistic clay model of her face. 

She's been working with prosthetic makeup designer Mike Marino, who's collaborated with her for years, bringing his expertise from films like The Penguin and A Different Man.

Klum's annual Halloween party is a spectacle, attracting celebrity couples and stars showcasing their best coordinated costumes. She's been hosting the event since 2000, but it took years to elevate to her current level of elaborate prosthetics.

"I'm hard at work already," Klum teased on The Tonight Show with Jimmy Fallon. "I'm gonna be extra ugly and super scary. Let's not ruin it. We have exactly 86 days, but who's counting?"

Klum's past looks have included a sultry Jessica Rabbit, a dazzling peacock, and a grotesque giant worm. This year's costume promises to be her most unforgettable yet, with fans speculating she's dressing as The Grinch or Beetlejuice.
