Model Heidi Klum celebrated the 25th anniversary of her Hollywood Halloween party in a gripping costume — she came as a giant walking severed hand. This is an extreme extremity. Apparently, Klum's a hand model in a big way. We'll try to keep the hand puns to a minimum; we pinky swear.

She definitely deserves high fives for this outlandish outfit. Sorry, couldn't resist. (WATCH)

We covered Klum’s Medusa costume last year.

Klum has shocked and surprised with her wild getups for a quarter century. Here’s an overview. (WATCH)

Klum’s yearly frights are created by a special effects studio called Prosthetic Renaissance.

Some costumes are easier to wear than others. (WATCH BOTH)

She has to be wearing an adult diaper or something similar.

It turns out Klum knows her costume like the back of her hand. (WATCH)

Maybe next year’s amazing feat will be her amazing feet. She’ll arrive by toe truck, of course.
