New York, New York - The best kept secret of spooky season has been revealed. And as expected, Heidi Klum – the Queen of Halloween – delivered with an amazing costume!

After a two-year hiatus, due to Covid, Klum was able to throw her huge Halloween bash once again and she used all that pent-up energy to truly outdo herself with an incredible outfit.

The 49-year-old turned up as a giant, extremely disturbing worm!

The creepy crawly costume didn't have armholes, and the supermodel had to wiggle her way into the party. Heidi's only recognizable features were here eyes and mouth – the rest was just one big gooey mass.

Tom Kaulitz, Heidi's husband, joined in the fun and came along as a scary fisherman in waders, as well as a gory prosthetic eye.

On Instagram, Heidi Klum shared a bunch of vids and pic depicting her Halloween transformation from model into worm. The process was clearly long and complex. It started out with a huge foam body, and ended with tons of prosthetic face pieces and paint.

The Queen of Halloween and her hubby clearly put in a ton of effort to look amazingly disgusting for Heidi's 21st annual Halloween party.

They weren't the only celebrities to show up in extravagant costumes.

Elon Musk took a break from his Twitter take over to dress in red leather armor for the monster mash. Kanye West's ex, actor Julia Fox, came dressed like a devil. Heidi's daughter Leni Klum also made an appearance at the big bash dressed as Catwoman.

The only question that remains is: was Heidi's wormy transformation enough to fend off the competition this year? She had some stiff competition this year from Kim Kardashian and Lizzo, among others.
