Heidi Klum Teases Her 'Extra Ugly' 2025 Halloween Costume

When it comes to Halloween, no one does it bigger (or weirder) than Heidi Klum.

For more than two decades, the 52-year-old supermodel has reigned as the undisputed Queen of Halloween, turning her annual Heidiween party into a can’t-miss spectacle for celebrities and fans alike.  From jaw-dropping prosthetics to cinematic-level costume reveals, Klum has made it clear that October 31 is her personal runway, and she’s not stepping off of it anytime soon.

Now, with Halloween 2025 just around the corner, Heidi Klum is already hard at work planning her next wild transformation, and according to her, it’s going to be one of her most terrifying yet.

During a Wednesday night appearance on "The Tonight Show Starring Jimmy Fallon," the "Project Runway" icon confirmed her infamous bash is officially returning.

“Of course!” she told Fallon when asked about the party. “I’m hard at work already. Like, already months ago.”

As for what fans can expect this year? Klum kept it cryptic, but creepy.

“Ooh, I’m going to be extra ugly,” she teased. “And super scary.”

Fallon tried to press for more, even asking if she’d be coordinating again with husband Tom Kaulitz, as she’s done in past years. But Klum was tight-lipped. “Let’s not ruin it. We have exactly 86 days, okay? But who’s counting?” she joked.

Klum also took a moment to reflect on her Halloween evolution, with Fallon pulling up a photo from her very first party back in 2000.

“Well, this is boring, I have to say,” Klum laughed, referencing her early Heidi-themed dirndl costume. “Over the years, I’ve met amazing people, and they help me now. They put prosthetics on me.”

And help, they do, because Klum’s Halloween looks have only grown more ambitious (and bizarre) with each passing year.

Here’s a look back at some of her most unforgettable costumes in recent memory.

In 2024, Klum stunned fans by transforming into a female version of E.T., the beloved alien from the classic film.

Dressed in full prosthetics with glowing features, she shared the spotlight with her husband, Tom Kaulitz, who portrayed the original E.T. character.

The year before, in 2023, Klum wowed attendees by appearing as a towering, vibrant peacock in a stunning blue and green ensemble. She even had a full team of performers dressed as her tail feathers, adding theatrical flair to the elaborate costume.

In 2022, Klum made headlines once again with what may be her most bizarre and talked about look to date, a disturbingly realistic worm.

She wriggled down the red carpet encased in a glossy, segmented body, while Kaulitz played her fisherman counterpart. The costume sparked both admiration and discomfort, proving her dedication to shock value.

Back in 2021, with her annual party canceled due to the pandemic, Klum pivoted to filmmaking. She produced a horror short film in which she rises from the grave and slowly morphs into a zombie mom while raising her kids.

Back in 2018, Klum stunned fans by showing up as Princess Fiona from "Shrek."

After teasing her costume on Instagram, followers guessed everything from George Washington to a "Star Wars" Gungan, but she threw everyone off with a full green face, ogre ears, and head-to-toe prosthetics. Husband Tom Kaulitz joined her as Shrek, and the couple instantly became Halloween royalty.

Then there was 2016, the year Klum quite literally dressed as herself. In a hilarious meta moment, she strutted into her party in full Victoria’s Secret glam, accompanied by a crew of five doppelgängers also dressed as “Heidi.”

With a Halloween résumé that includes clones, fairytale creatures, aliens, insects, and full horror-movie productions, Klum has proved that when it comes to Halloween, she doesn’t just play dress-up. She puts on a show.

And with promises of being “extra ugly” and “super scary” in 2025, it sounds like Heidiween is far from running out of tricks.
