Heidi Klum, a master of Halloween, teased her much-anticipated costume to her nearly two million followers on Instagram on Oct.2 ... but we're not quite sure what it is.
"It's almost time for my favorite holiday! Costume prep time with the team at @prorenfx Can't wait for Halloween! 🎃" she captioned a photo of herself covered in a plaster molding with a seemingly-horned headpiece.
"So yucky but so worth it in the end 🎃 #heidihalloween#heidiklumhalloween" she said with a photo of her face covered in goop.
It seems as though the most special part of the holiday for Heidi is the suspense.
"I always like to surprise. I don't like to tell people what I'm gonna do because people have a certain expectation of what it's gonna be like. I like to just show up and not tell anyone what it's gonna be," she recently told US Weekly.
Over the past few years, Heidi has transformed into a psychedelic butterfly, an old woman, a gorilla, Cleopatra and more outrageous getups.
