Kate Hudson attracted a scary number of celebrities at her annual Halloween party and RadarOnline.com has the photos.

From Gwen Stefani and David Arquette to Jessica Alba and Nicole Richie A-listers poured into Hudson's Pacific Palisades home for the fright night festivities.

Leaving the usual skimpy attire reserved for Halloween at the door Rashida Jones covered up in a Cherry Blow Pop costume and Stefanie stole the show with her floor length Cinderella gown.

Other costume clad revelers included Ali Larter as a bumble bee, Emma Roberts as a Playboy Bunny and Nicky Hilton as Little Red Riding Hood.

Arquette attended with his Dancing with the Stars pal Chaz Bono, who left the costumes to others.
