Is That You, Heidi? Ms Klum Goes As Old Granny To Her Legendary Halloween Party

We can't imagine that Heidi Klum will EVER look like this, can you? But the supermodel made a VERY convincing granny for her 14th Annual Halloween Party, held at Marquee New York in West Chelsea.

The stunning star, 40, was completely transformed into a little old lady by makeup maestros Bill Corso and Mike Marino. She donned a bald cap and sported scarily lifelike varicose veins, liver spots, wrinkly skin and even a hunched spine.

She completed the look with granny chic, including pearls, a tweed skirt suit, a white wig and a cane.

According to the Daily Mail, Heidi takes her Halloween costume very seriously. In an interview with Parade magazine, she said: "I start thinking of ideas months before Halloween, and I have an amazing team who makes the impossible possible. I don't really have a system for picking my costume each year, they kind of just come to me. It's definitely not a last-minute decision. It takes months of preparation."

The star posted a series of Instagram pics showing her getting ready, one which read: "Fun times!"

Another showing a close-up of her varicose veins and wrinkly knees, that simply said: "Wow."

And one showing the wrinkly face and neck coming to life:

Heidi's intricate Halloween costumes are legendary, and she has wowed in a skinless Hellraiser costume, as a black crow, and as the Hindu goddess Kali. What do you think of this year's (big) effort?
