Hollywood has always treated Halloween like its own private masquerade, a night where stars trade red carpets for cobwebs and glamour for ghoulish delight. Every October, the industry’s brightest step into the dark, cloaking themselves in creatures, villains, and fantasies that blur the line between beauty and terror. Cameras flash, but beneath the glitter, there is something deliciously sinister, a hunger to outdo, outshine, outspook. And after years of playful fright, the transformation reached its peak; the celebrity looks in 2025 were the eeriest of them all.

Hollywood’s biggest names turned Halloween 2025 into a chilling spectacle. Think Heidi Klum’s haunting transformation, Ed Sheeran’s unexpected dark twist, and other celebrities whose looks redefined spooky glam forever.

Heidi Klum’s Medusa costume was a cinematic masterpiece that blurred the line between myth and reality. She wore a full serpent bodysuit shimmering with green and gold scales, a long mechanical tail that coiled behind her, and a crown of lifelike snakes that twisted and hissed as if alive.

Her face was adorned with fangs, reptilian makeup, and piercing eyes that seemed to petrify on sight. Completing the illusion, she wielded a bow and arrow, flicked a forked tongue, and hissed menacingly at flashing cameras.

Ed Sheeran took Halloween to spine-chilling new heights, transforming into Pennywise, the menacing clown from Stephen King’s It. The singer was utterly unrecognizable in fiery red hair, cracked white makeup, and the signature sinister grin. He roamed New York City clutching a red balloon, casually sipping coffee, grabbing pizza, and even downing a beer at a pub while in full horror mode.

His Instagram caption, “In for a Penny,” perfectly captured the eerie humor of it all, turning the streets into his very own haunted playground.

Demi Lovato brought internet lore to life by resurrecting her infamous alter ego, Poot Lovato, for Halloween 2025. The singer recreated the viral 2015 meme with eerie precision, donning the same pale lighting and uncanny expression that birthed the legend. On Instagram, she posted a side-by-side of the original photo and her chilling recreation, posing in a dim garage as if Poot were escaping captivity.

She completed the act with a TikTok skit, screaming for help and clawing at the door, fully embracing the haunting humor.

Janelle Monáe turned heads with a perfectly executed Halloween transformation, stepping onto The Jennifer Hudson Show as Mike Myers’ 2003 version of Dr. Seuss’ Cat in the Hat. Every detail was flawless, from the towering red-and-white striped hat to the oversized bow tie and fuzzy black-and-white suit.

In a video shared on the show’s official Instagram page, Monáe strutted confidently down the hallway, dancing and striking playful poses. The post’s caption summed it up best: “@janellemonae is Cat in the Hat! Style so sharp, there’s no topping that!”

The spine-chilling parade did not stop there. Three more celebrities stepped up with eerie, unforgettable looks that defined Halloween 2025.

Blackpink’s Lisa turned Halloween 2025 into a golden spectacle, transforming into the mystical siren from Love, Death + Robots’ Emmy-winning episode Jibaro. She embodied the Golden Woman with metallic gold paint, a shimmering suit of chains, beads, and layered fringe, topped with a sculpted headpiece and gem-studded red lips.

On Instagram, she shared photos captioned “Jibaro 👑👻,” along with a mesmerizing clip posted on LLOUD’s page, where she mimicked the siren’s haunting movements, an ode to greed, beauty, and destruction that left fans spellbound.

Paris Hilton brought pure magic to Halloween 2025 with a whimsical family transformation inspired by Peter Pan. The entrepreneur shimmered as Tinker Bell, wings sparkling and wand in hand, while her children, London Marilyn Hilton Reum and Phoenix Barron Hilton Reum, charmed as Wendy and Peter Pan.

Husband Carter Reum embraced his inner villain as Captain Hook, complete with a towering hat, gleaming sword, and signature hook hand. Hilton shared the enchanting family photos on Instagram, giving fans a glimpse into their dreamy Neverland adventure.

Lady Gaga turned Halloween 2025 into a high-fashion fever dream, channeling the Garden of Eden from her latest album Mayhem. She dazzled in a corseted gown adorned with red and pink floral appliqués, complete with a dramatic feathered headpiece. Sharing the ethereal look on Instagram, the singer described herself as both the garden and its keeper,  a poetic nod to her ever-evolving artistry.

While these seven divine costumes quickly became the most talked-about of the year, Heidi Klum’s 2025 look outshined her infamous 2015 outfit that went down as one of Halloween’s least popular looks.
