The Project Runway star initially cancelled her star-studded Halloween gala after Hurricane Sandy devastated New York City last Monday (October 29).
She tweeted at the time: "Hope you & your loved ones are safe after the storm. Cancelling my Halloween party...postponing to a haunted Christmas."
Klum has now decided to hold the spooky celebration on December 1, an insider revealed to Page Six.
The supermodel tweeted last week that she planned to dress as Egyptian queen Cleopatra for her original Halloween bash, but it is unclear if she will wear that costume at the rescheduled event.
Klum will be back in her native Germany next week to host the 2012 MTV Europe Music Awards, airing on MTV channels around the world on November 11 from Frankfurt.
