Heidi Klum transforms into old woman for Halloween

Heidi Klum is known for her red carpet ensembles, but you've never seen her quite like this.

The model transformed herself into an old woman for her annual Halloween party on Thursday night.

Klum, 40, was virtually unrecognizable thanks to a white-haired wig, wrinkly skin, liver spots and the cane she arrived to the fete with.

Once it was finished, she shared another photo of the final look:

Klum has earned a reputation for going all-out with her Halloween costumes. In previous years, she's gone as Cleopatra, an alien robot, the apple and serpent from the Garden of Eden and a Hindu goddess.
