It's the most wonderful time of the year for Heidi Klum! The 40-year-old supermodel will be celebrating Halloween on Thursday, Oct. 31 ,with her annual A-list party, this time at Marquee nightclub in New York City. Every year Klum goes all out with her costumes -- and this year appears to be no exception.

The Project Runway host tweeted sneak peek photos of herself getting ready for her holiday bash on Twitter Thursday afternoon. "Ok guys........I am going into the future," she teased with a "before" look of her sitting in a makeup chair.

One hour later, Klum shared a photo of herself with her back to the camera while three makeup artists worked on her face. The German model's long blonde hair was covered with a bald cape and her bare back was exposed.

She later posted a third photo to show fans the progress. In the snapshot, four makeup artists are working on her legs while a fifth one applied makeup to her arm. She appeared to be wearing a short black strapless dress while sitting in a high directors chair. Her team had a large table set up filled with body paint.

In a fourth image, Klum shared a closeup shot of her makeup artists Bill Corso and Mike Marino applying a mask to her face and neck to make her look old and wrinkly.

Klum has previously transformed herself into Cleopatra in 2012, an ape in 2011, an alien robot in 2010, a black crow in 2009 and a Hindu goddess in 2008 -- to name just a few. Last year, Klum decided to postpone her Halloween party until Dec. 1 due to Hurricane Sandy hitting the East Coast. Her 2012 party marked her first Halloween since splitting from husband Seal in January of that year after seven years of marriage.
