Heidi Klum has revealed the inspiration behind her most gruesome Halloween costume yet.

The “Queen of Halloween” was unrecognisable as she unveiled her latest creation, a severed hand, at her 25th edition of the much-anticipated annual party.

As for what inspired the grisly costume, the model told the Associated Press: “My left hand inspired it. I looked at my hand, and I thought, ‘Hey, I think that I can fit my body inside of this somehow’, you know? And they did. They fit it inside.

“Every year I always try and come up with something that is unusual. I don't think I've seen an actual person walking around like a hand.”
