Heidi Klum is getting into the spooky season spirit.
The America's Got Talent judge—known for wearing extravagant costumes to her annual Halloween party—gave fans a sneak peek at what she'll be rocking at this year's bash, sharing a photo of herself in what appeared to be a brown compression bodysuit meant to be worn under prosthetics.
"There’s a clue here," she captioned the Oct. 7 snapshot, which also showed her raising a clawed hand, "but I just can’t put my finger on it."
And Heidi's costume has been months in the making. In fact, she shared a snapshot of a glass eye in August, writing at the time, "I see a clue of what’s to come on October 31 … can you?"
She followed up the cryptic post with videos of what appeared to be prosthetic molds, before posting a clip of herself wearing the brown bodysuit as workers from Prosthetic Renaissance—the company behind Colin Farrell's unrecognizable transformation in The Penguin—took her measurements.
"There goes a lot into it," she recently told People of her costume preparations, "because I wanted to be so spectacular that this is not something I can just throw together overnight."
She continued, "It takes a long time. It takes a lot of planning. And also then when I do the reveal, I want to have a special reveal because I know I have so many fans and those particular Halloween fans are people who love also dressing up and coming up with amazing things."
Heidi previously worked with Prosthetic Renaissance to transform into Jessica Rabbit, Fiona from Shrek and the werewolf from Michael Jackson's "Thriller" music video. In recent years, Heidi took her costume up a notch by incorporating other characters—like in 2022, when husband Tom Kaulitz dressed up as a fisherman opposite of her epic worm costume.

And last year, the supermodel had nine acrobats serve as the feathery wings in her jaw-dropping peacock costume.
“I always try to find things that people naturally wouldn’t do," Heidi told People. "Most people do nurses or police officers, but I was always looking for something that I hadn’t seen."
