Today 8:15 PM PDT by Marianne Garvey



She may have quit Victoria's Secret, but supermodel Heidi Klum is still ready to get dolled up in some funky outfits.

Yes, Klum exclusively tells E! News that she's busy preparing for her annual over-the-top Halloween extravaganza.

And we have all the details...

Klum has moved the festivities back to New York this year—and some, um, extreme measures were taken in finding the right location. Doorway heights had to be measured and space interiors checked to make sure her costume would fit through and that she'd have room enough to move around comfortably inside.

"I like to change things up," Heidi hints to E! News about her costume. "This year is back in New York and my costume is larger than life! I hope everyone will try to out do me! The game is on!"

Could this be the frightfest to top all the others?

"No one knows exactly what the costume is yet, Heidi won't tell anyone, but it is over 8-feet tall and she had to find a location where the doorway would fit her walking in in full costume," an inside source tells E! News.

"This year's costume is going to be better and definitely bigger then ever."

Could it be a Snooki pouf? We'll have to wait and see. What we do know is that Klum has been hard at work on the costume for the past nine months.

For the past two years, she's has held the bash in Los Angeles, and is excited to be returning to Manhattan, where it will be held at LAVO nightclub. (Note to Lamar Odom: Hope you were invited, you'll love the door.)

Expect many celeb twitpics to come from the big night—Klum is installing a state-of-the-art photo booth so guests can upload their costumed selves on to Twitter.

Klum persuaded ?uestlove of The Roots to take a break from Late Night With Jimmy Fallon to DJ and Stella Artois will be served.

Expected at the 11th annual party are Eva Longoria Parker, Kristin Chenowith, Jessica Alba, Klum's hubby, Seal, and her beloved Project Runway winner Christian Siriano.
