The Queen of Heidiween Has Entered the Chat

When it comes to Halloween, no one — and we mean absolutely no one — does it quite like Heidi Klum. Every year, while the rest of the world debates between a witch hat and a store-bought vampire cape, Heidi is spending months in prosthetics, planning a full-scale transformation that leaves even her closest friends doing a double take. She is not just dressing up. She is putting on a production.

Since the year 2000, Heidi Klum has hosted her annual A-list Halloween party, wearing increasingly elaborate costumes that often leave her completely unrecognizable. That tradition, which fans and media have lovingly dubbed “Heidiween,” has grown from a fun celebrity get-together into one of the most talked-about nights in pop culture. Each October, the world holds its breath and asks the same burning question: what did Heidi Klum dress up as for Halloween this year?

This article takes a look back at every iconic Heidi Klum Halloween costume over the years — from her early days riding into a party on a horse to her spine-chilling 2025 Medusa reveal — and explores what makes her the ultimate Halloween icon.

How It All Started: The Origin of Heidiween

It is hard to believe that the same woman who later arrived at parties as an eight-foot-tall Transformer and a full-body worm once showed up in a comparatively tame all-black Dominatrix costume. But that is exactly how it started. In 2000, Heidi Klum threw her very first Halloween party — and while the Dominatrix look was bold, it was just a hint of the madness to come.

By 2001, things escalated quickly. For her second annual Halloween bash, Klum pulled off what can only be described as a power move: she rode into the event on a real horse to complete her Lady Godiva costume. That moment was the turning point. It signaled to the world that Heidi Klum was not here to play it safe — she was here to make history.

The early years continued to build on that momentum. In 2002, she channeled the animated flapper caricature Betty Boop. In 2003, she leaned into the abstract with a mysterious gold extraterrestrial look that had guests scratching their heads. By 2004, she was a fiery red witch — and the party was already becoming one of the most anticipated events of the New York City social calendar.

What started as a fun celebrity Halloween party had evolved into something much bigger. Heidi Klum Halloween party became a yearly spectacle, a red-carpet event that A-listers scrambled to attend, and a pop culture moment that people dissected online for days.

Heidi Klum Halloween Costumes Over the Years: The Most Iconic Looks

If you have been following Heidi Klum Halloween costumes over the years, you already know that she does not do anything halfway. Here is a rundown of her most jaw-dropping, most memorable Heidi Klum Halloween outfits through the years.

2008 — Kali, Goddess of Destruction

Few Heidi Klum Halloween costumes have been as visually overwhelming as her 2008 look. That year, she transformed into Kali, the Hindu goddess of death and destruction, complete with multiple arms, dangling heads, and a deep coat of blue body paint. It was theatrical, it was bold, and it cemented her reputation as someone who did not shy away from a costume challenge.

2010 — The Transformer

Standing nearly eight feet tall, Heidi Klum arrived at her 2010 Heidi Klum Halloween party decked out head-to-toe in a purple and red Transformer costume. This was not a costume you bought off a rack — this was a full-on mechanical marvel that required serious engineering. Guests were reportedly stunned.

2011 — The Human Body (Her Personal Favorite)

Ask Heidi which of her Heidi Klum costumes is her all-time favorite, and she will tell you: the human body. In 2011, Klum arrived at her party on a gurney pushed by two bloodstained doctors, dressed as a full cadaver with every muscle visible beneath her “skin.” It looked like a page ripped straight out of a biology textbook. Utterly creepy, utterly brilliant.

2015 — Jessica Rabbit

In 2015, Heidi Klum swapped the grotesque for the glamorous — but still kept the prosthetics. She dressed as Jessica Rabbit, the animated femme fatale from Who Framed Roger Rabbit?, and she did not hold back. “I wanted to be the ultimate male fantasy,” she said of the look, which featured heavy prosthetics and an exaggerated, cartoonishly feminine frame. The result was stunning.

2017 — Thriller Werewolf

Channeling Michael Jackson’s iconic music video, Klum transformed into a Thriller-era werewolf in 2017, complete with torn clothes, wild makeup, and a look that was equal parts frightening and fun.

2018 — Princess Fiona

Shrek fans, this one was for you. In 2018, Heidi Klum dressed as Princess Fiona from Shrek, complete with prosthetic ears, hands, and full green makeup. It was one of her most recognizable and beloved costumes, and the attention to detail made it look like Fiona had literally stepped off the animated screen.

2022 — The Worm (A Return to Glory)

After a two-year hiatus during the pandemic, Heidi Klum Halloween was back — and she made sure nobody forgot she had been gone. For 2022, Klum revealed she was dressed as a massive, slimy worm. Yes, a worm. “I just wanted to be something random. I don’t think I’ve ever seen anyone being a rain worm before,” she explained. Her husband Tom Kaulitz accompanied her as a fisherman, completing the couple’s costume. Heidi Klum Halloween 2022 instantly became one of the most memed and talked-about celebrity Halloween moments of the year.

2023 — The Peacock

If the worm was weird, the peacock was pure spectacle. For Heidi Klum Halloween 2023, she arrived as an enormous, vibrant peacock — a costume so massive and theatrical that it required 15 additional performers to help navigate it. The look was visually stunning and took the production value of Heidiween to a whole new level.

2024 — E.T. the Extra-Terrestrial

For Heidi Klum Halloween 2024, she went intergalactic. Channeling the beloved alien from Steven Spielberg’s 1982 film, Klum transformed into E.T. — and in the creepiest, most genius detail — her actual face was hidden inside the costume, with just her eyes eerily peeking out through E.T.’s neck. Husband Tom Kaulitz also dressed as E.T., making it a matching extraterrestrial couple’s moment. Klum later described it as one of the most technically demanding costumes she had ever worn.

Heidi Klum Halloween Costume 2025: Medusa Takes Over New York

So what was Heidi Klum for Halloween this year? In 2025, she became a monster of mythological proportions.

For the Heidi Klum Halloween party 2025, the supermodel transformed into Medusa — the serpent-haired Gorgon from Greek mythology whose gaze could turn anyone to stone. And true to form, she did not do it lightly. Klum emerged at the Hard Rock Hotel New York in a reptilian, hand-painted bodysuit crowned with a massive headpiece of writhing, moving snakes. She had a prosthetic forked tongue, fake snakes coiling from her head, a rattlesnake tail, scales covering her face and body, and piercing bright green contact lenses. The result was genuinely terrifying.

“HAPPY HEIDIWEEN 🐍 Don’t stare too long or you’ll turn to stone,” she captioned her Instagram reveal, adding the hashtag #HeidiHalloween.

Leading up to the event, Klum had teased the look on social media — sharing glimpses of pointed fake teeth and green face paint — without giving too much away. She had also told People magazine: “I’m going to be very ugly because I always try to do something different.”

And if Heidi was Medusa, what was Heidi Klum Halloween 2025 guests’ highlight? Tom Kaulitz stole the show alongside her, dressing as a Greek soldier who had been turned to stone — a perfectly choreographed complement to her mythological monster look. Kaulitz, ever the charming husband, reportedly told guests he still found his wife “sexy” despite her terrifying transformation.

The Heidi Klum Halloween costumes 2025 era officially marked the 25th anniversary of her legendary annual bash, making it a milestone moment in Heidiween history.

Behind the Scenes: The Making of a Heidiween Costume

If you have ever wondered how Heidi Klum Halloween costumes go from concept to reality, the answer involves months of planning, a world-class team of special effects artists, and an almost obsessive level of dedication.

Klum has said that she starts thinking about her next costume almost immediately after Halloween ends. The planning is year-round — sketches, fittings, testing prosthetics, sourcing materials, and coordinating with her team. She often tags prosthetic makeup artist Mike Marino as a key collaborator on her looks. Marino is no small name in Hollywood — he has worked on major film productions including The Penguin and A Different Man, lending his skills to Klum’s annual Halloween spectacle.

In recent years, Klum has also gone live on Amazon during her getting-ready process, teasing fans with behind-the-scenes glimpses while keeping the final reveal a surprise. It has become part of the Heidiween experience — a social media countdown that fans genuinely look forward to each October.

The hours spent in the makeup chair are staggering. Some of her most complex costumes have required upwards of five to eight hours of prosthetic application alone. Add in the costume construction, the performer rehearsals (looking at you, 2023 Peacock), and the full production setup of the party itself, and you start to understand just how seriously Heidi Klum takes Halloween.
