In Girl World, Halloween is the one night a year when a girl can dress up like a total slut and no other girls can say anything about it, according to the film Mean Girls. In Heidi Klum World, Halloween is for outrageous costumes that continue to top all previous years.

Heidi Klum, who is known as a super-supermodel, is also quite festive every year for Halloween, throwing massive parties with hubby Seal and wearing outlandish costumes. This year, Klum gave a sneak peak of her nearly completed costume, or rather costumes for the two parties she is hosting, days before Halloween.

Klum will be a bald and hairy monkey on Halloween night for her annual party in New York and a barebones skeleton she calls The Visible Woman on Saturday in Las Vegas.

After offering the world a hint, it is a little bit hairy, Klum unveiled both of her Halloween costumes on Tuesday as they underwent the finishing touches.

The Visible Woman costume was hand-painted by designer Martin Izquierdo, according to People. Klum will wear that costume Saturday at Tao Nightclub at the Venetian in Las Vegas. Following, the 38-year-old supermodel turned mom will monkey around at her annual soiree held at New York City's PH-D Rooftop Lounge

Klum, who always goes extreme for Halloween, always makes her own costumes.

The amazing thing about creating your own costume is that you can be sure no one else has the same, she had said.

In the past, Klum has been a Transformers-esque alien robot, a scary Indian goddess, a cat, an apple and giant superhero.

Halloween is probably one of my favorite holidays of the year because I love costumes and I love to be innovative and I love to dress up, Klum said.

In light of this, Klum is having a Halloween costume for children to select the ten most unique, most special costumes. The Little Pumpkin Costume Challenge, in association with Patch, offers a chance to win a trip to New York and $1,031 for a charity.

Klum's love for Halloween is not unaccompanied; Her husband singer Seal and four children love the October holiday too.

If it was up to them, we'd go to a pumpkin patch everyday, and they would wear costumes everyday, Klum told US Weekly last October. They would keep the spiders, hanging in our house for the rest of the year. They just love it!

Heidi Klum also wrote an article for AOL in honor of Halloween, highlighting her five favorite costumes for couples. Her choices? Siegfried and Roy, Catch of the Day (a fisherman and a mermaid), Touchdown (a football player and cheerleader), Youre under arrest! (a cop and an arrestee) and Tarzan and Jane.
