Heidi Klum unrecognizable in elaborate giant worm costume at her New York City Halloween bash

Heidi Klum revealed her highly-anticipated Halloween costume on Monday night, shocking and terrifying Instagram users as a realistic-looking gigantic worm.

The former model, who throws extravagant Halloween bashes every year, is known for her love of epic costumes. She held her 21st Annual Halloween Party on New York City’s Lower East Side.

Her spooky get-up was part of a couple’s costume. Her husband, Tom Kaulitz, was dressed as a fisherman with a bloody eye.
