Inside Heidi Klum’s Star-Studded Halloween Bash

Darren Criss, best known from “Glee,” arrived with his wife Mia Swier dressed as Shrek and Puss in Boots — a playful nod to DreamWorks’ classic characters. Social media couple Campbell “Pookie” Puckett and Jett Puckett turned heads as Elvis and Priscilla Presley, bringing vintage glamour to the night.

Rei Ami, the breakout artist and voice actor from “KPop Demon Hunters,” channeled her animated alter ego Zoey, blurring the line between fiction and reality. Model Alexis Ren, Olympic athlete Ilona Maher, and influencer Gigi Gorgeous also made stunning appearances, while Anna Ermakova and Damian Hurley added runway flair to the red carpet.

Heidi Klum herself once again outdid expectations. Having teased her costume months in advance on television, she revealed an elaborate creation that involved special effects prosthetics designed by her longtime collaborator, Mike Morano. Over the years, Klum has transformed into jaw-dropping characters like Jessica Rabbit, a worm, and even an otherworldly alien, but her 2025 look was among her most ambitious yet.

In an interview earlier this year, Klum shared that she begins planning her Halloween costume months in advance, working closely with makeup and prosthetic artists to achieve movie-level detail. Her dedication has inspired many of her celebrity guests to elevate their own costume game each year.
