Whie Heidi Klum, 39 who annually wows with her New York Halloween party extravaganza, has called off the festivities this year due to people stuck in the aftermath of Hurricane Sandy, there are still tons of celebs who have not had their Halloween festivities interrupted, including Kim Kardashian, Jessica Alba, Stacy Keibler and Katie Featherston.

While Kardashian celebrated Halloween over the weekend by hosting her second annual Midori Halloween bash in New York before the hurricane hit, she still dressed up as a platinum blonde, emerald-colored (or, Midori-colored?) mermaid … in case she had to weather the storm? Which, of course, meant that her beau Kanye West was decked out as a sea captain to the rescue. "Why not experiment?" Kardashian told InStyle of her Halloween philosophy. "If you have a crazy idea you've been wanting to try out, I say go for it! It's Halloween — more is more."

Paranormal Activity's Featherston has a bit of that coveted Pippa Middleton look already, and she's going to maximize it for Halloween, dressing up as the world's most beloved royal sister-in-law and former maid of honor, she told Uinterview exclusively.

In adherence to her superhero roots, Fantastic Four's Alba, her hubby Cash Warren, and their two little ones dressed as the cast of Pixar's The Incredibles for their Hollywood Halloween party at Gwen Stefani's place, and George Clooney's lucky gal Keibler kept it simple, masquerade-style, in a sexy black dress, green nailpolish and a flattering mask seductively covering her eyes and cheeks.

But when it comes to keeping it simple, Victoria's Secret model Adriana Lima had everyone beat, posting a photo on her Facebook page of herself wearing some sexy black lingerie and a headband with devil's horns. "Taking a day off from being an angel for Halloween," she tweeted. "What's everyone dressed up as? Love, Adriana."

And singer-songwriter Michelle Branch teased her costume tonight by tweeting an old pic of Taylor Swift, who dressed up as her a few years ago for Halloween. "Remember that Halloween when @taylorswift13 dressed up as me?" she tweeted, with the picture. " … maybe I should dress as her tonight?!" We'll have to wait and see.

As for Klum's Halloween party postponement, however, don't lose heart. In lieu of Halloween, Klum, who dressed in two costumes last year — a dead, flayed body a la "The Bodies" exhibit, and a very realistic-looking monkey with hubby at the time, Seal — promises a "haunted Christmas" on Twitter.
