Hollywood’s biggest stars brought their boldest looks to Heidi Klum’s iconic Halloween party on Saturday night.
The annual fright-night celebration featured daring red-carpet outfits, elaborate transformations and eye-catching celebrity tributes, as A-list guests battled to deliver the most memorable costume of the evening.
The barely-there arrivals gave photographers plenty to capture, but the spotlight was always destined to fall on one guest in particular.
Klum, who was marking the 25th anniversary of her legendary Halloween bash, lived up to her reputation with a stomach-churning transformation that was, quite literally, a bloody handful.
Model Vanessa Fuchs made one of the night’s boldest entrances, channeling Natalie Portman’s character Alice from Closer in a pink wig, purple lingerie-inspired outfit with white fringe and a dramatic white fur coat.
Haley Kalil brought comic-book glamour to the red carpet as the famously curvaceous Jessica Rabbit. Model Kim Hnizdo opted for a metallic silver corset and matching briefs, finishing the daring look with white body paint.

Even with so many elaborate costumes competing for attention, there was only ever going to be one undisputed star of the night.
Klum, who celebrated the 25th anniversary of her annual Halloween extravaganza, arrived at New York’s Cathédrale restaurant in one of her most bizarre getups yet.
The German supermodel became a gigantic, gruesome replica of her own severed left hand, complete with enormous fingers, long red nails, dangling tendons and blood dripping from her mouth.
Only her eyes and mouth were visible through the elaborate prosthetics, while assistants dressed in blood-stained hazmat suits helped bring the disturbing vision to life.
The look was masterminded by her longtime special-effects collaborator Mike Marino, with the elaborate costume taking months of planning and around four months to make.
The star later stripped away her costume’s outer layer and unveiled a second look that was just as horrific, pairing gory face prosthetics and a blonde wig with her existing set of massive, finger-like leg prosthetics.
Heidi revealed that getting into the creation took approximately five to six hours, admitting that carrying the enormous costume was particularly challenging.
Even her wedding jewelry was recreated as part of the look, with replicas of her engagement and wedding rings and the tattoo of husband Tom Kaulitz’s name on her ring finger.

Klum also shared her look via her Instagram, writing: ‘TALK TO THE HAND ✋ #HeidiHalloween 2026 HERE WE GO.’
And ahead of the event, which she’s been hosting since 2000, the star teased her costume on social media.

Meanwhile, her daughter Leni put on a pig nose and ears with long blond hair and a pale-pink robe to become Miss Piggy of The Muppets fame.

Last year, Klum arrived at her party dressed as Medusa from Clash of the Titans.
In past years, Klum’s other costumes have included transforming into E.T., a peacock, an alien and Princess Fiona from Shrek.
However, her most famous costume of all might have been the one that she wore in 2022.
At the time, Klum arrived as a worm, slithering around on the floor.
She was totally transformed, and you could barely recognize that it was the supermodel underneath the thick layers.
The costume was so realistic that it instantly went viral, lighting up the internet.
To make the costume come to life, she worked with Mike Marino, owner of Prosthetic Renaissance, a special effects company that has made tons of realistic-looking Halloween costumes over the years.
Her husband, Tom Kaulitz, completed the other half of her costume as a fisherman.
In an interview with The Hollywood Reporter at the time, Klum admitted that she felt ‘claustrophobic’ while wearing the elaborate costume.
‘I was so claustrophobic in that costume,’ Klum shared.
‘It is one thing to add prosthetics to your body — but to be stuck inside the worm body and not really be able to use my arms or feet was not very comfortable,’ she said.
