Heidi Klum Teases ‘Very Ugly’ 2025 Halloween Costume With ‘Cheeky’ Prosthetic Molds

Fresh prosthetic teasers, including a tag to effects artist Mike Marino, keep fans guessing before her Heidiween reveal.

Overview

  • Klum posted a plaster cast of her back and bottom on Instagram with the caption “Feeling cheeky,” tagging prosthetic designer Mike Marino.
  • An earlier Oct. 1 post showed a 3D facial mold with the note “This is just the beginning,” signaling a prosthetic-heavy transformation.
  • She told People she plans to look “very ugly” this year and emphasized doing something different from recent turns as E.T. (2024), a peacock (2023) and a worm (2022).
  • Marino, who collaborated on her E.T. look, is credited again on the 2025 build and is known for high-profile film prosthetics work.
  • Fans are speculating about concepts on social media, including Bender, The Mask and a Han Solo carbonite homage, but no reveal has been confirmed and the party is set for later this week.
