Heidi Klum once again proved she’s the undisputed queen of Halloween as she hosted her legendary annual costume party in New York City. The event has long been the crown jewel of celebrity Halloween festivities, and 2025’s edition was no exception—bigger, bolder, and weirder than ever.

Every year, Klum’s party draws a glittering mix of A-listers, models, musicians, and reality stars who all arrive dressed to shock, stun, or amuse. Known for its exclusive guest list and strict no-entry-without-a-costume policy, the bash has become as anticipated as the Met Gala—just with more fake blood and latex.

This year’s celebration transformed the venue into a surreal nightmare-meets-fashion-show, filled with elaborate props, eerie lighting, and some truly unforgettable looks. Attendees didn’t just show up in costumes; they became their characters, blurring the line between performance art and pure Halloween chaos.

Klum herself has built a global reputation for going above and beyond when it comes to her own costume reveals. From her hyper-realistic Jessica Rabbit transformation to her jaw-dropping alien and worm ensembles, the supermodel has turned Halloween into her personal Olympics of creativity. Each year, fans wait eagerly for her grand entrance—an event so secretive that even her team keeps details under wraps until the big moment.

Her parties date back to 2000, when she first threw a Halloween event in New York that instantly made headlines for its outrageous costumes and star-studded guest list. Over the years, the celebration has moved through iconic venues like Marquee and Tao Downtown, each year raising the bar for extravagance and imagination. Klum’s passion for the holiday has made her the reigning monarch of spooky season, inspiring countless celebrities to bring their A-game or risk being upstaged.

And bring it they did. From spine-chilling monsters and flawless movie recreations to hilarious pop culture references, every guest seemed determined to make this year’s photo gallery one to remember. Some looks were works of art; others, well, had people wondering if they’d gotten lost on their way to a costume contest at a dive bar.

But that’s part of the magic. At Heidi Klum’s Halloween bash, there are no wrong answers—only unforgettable moments, wild creativity, and a spirit of fun that perfectly captures what makes Halloween so beloved. It’s not about who looks the best; it’s about who dares to go all in.
