Model Heidi Klum’s Halloween costumes are the stuff of holiday legend, so much so that she was trending on Google on Halloween evening.
Her costumes are often extravaganzas, and they’ve gotten more elaborate over the years. There was the time she dressed as an old lady version of herself. As Cleopatra. As the forbidden fruit, a werewolf, worm and a clone. And so on.
Some fans stayed up late just to see what Klum wore for Halloween 2025, comparing her Halloween reveals to Mariah Carey’s latest Christmas album.
What Costume Did Heidi Klum Wear for Halloween 2025?
Klum gave glimpses of her costume on her Instagram page. One video showed her getting a dinosaur-looking contact inserted into her eye, although one fan thought it looked like the grinch. Another person thought she was a gremlin.
“Is it in?” she wrote.
“Halloween is about to be over Heidi! šš¤¦š»āāļø I wanna go to bed but I been waiting all day lol,” a fan wrote.
“Inside out,” Klum wrote with another photo teasing the costume. “Girl Iām getting sleepy. Youāre the only reason Iām up. š©” a fan responded.
Another video Klum posted showed her getting green, rippled skin applied to her face.
“We wait for Heidiās Halloween costume like we wait for Mariah Careyās Christmas season kickoff video lolšš” a fan joked.
Klum also posted a photo showing her baring fanged teeth.
Another photo showed her holding a clump of wires. And in yet another tease video, a makeup artist applied green makeup to Klum’s face.
Heidi Klum Revealed That Her Halloween Costume Would Be ‘Ugly’
“No one does Halloween like @heidiklum! We had her rank her iconic Halloween looks and give us a tease for what she’s wearing this year š” Good Morning America wrote on Instagram.
“I’m going to be very ugly. And very scary. But very ugly,” Klum said in that interview.
She then ranked her past Halloween costumes, starting with her turn as Jessica Rabbit, the cartoon character. Klum revealed that she considers that costume to be a “7,” and indicated that some fans mistakenly thought she was going to be Kim Kardashian before the reveal. She said in the interview that she wanted to be a male fantasy with that costume.
Klum also said in that interview that she considers her iconic worm costume to be a “10.” She said she tried to mimic a worm crawling around the mud in the rain, and felt she succeeded, although it was difficult to move in the costume because she had no arms or legs.
She gave her ET costume another “10.”
