Heidi Klum reveals this year's stunning Halloween costume

Klum's over-the-top costumes have become a tradition. In recent years she has appeared as a peacock, a lifelike worm, from Princess Fiona Shrek and Jessica Rabbit, all with the help of heavy prosthetics and often spending hours in the makeup chair. She previously teased on Instagram: “You'll never guess what this year has in store.”

In a recent conversation with PeopleThe America's Got Talent The judge revealed she had been working on this year's costume for months, with time for molding, prosthetics and fittings.

“There's a lot that goes into it because I wanted to be so spectacular that I can't just pull it off overnight,” she said. “It takes a long time. It requires a lot of planning. And then when I do the reveal, I want to have a special reveal because I know I have so many fans, and those special Halloween fans are people who also love dressing up and making up fun things.”
