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.
