Last night Kate Hudson threw a huge Halloween party, one week ahead of the actual holiday.

The guest list reads like a who's who of the A-List, with Cindy Crawford pulling off a pretty good, albeit too pretty Amy Winehouse, Tobey Maguire and his wife Jennifer as a white trash couple, and Leo in a mask (sooo creative, right?).

Sasha Baron Cohen was udderly adorable as a cow, Courteney Cox looked hot as a witch, David Arquette matched his wife as a wizard, Kate's dad Kurt Russell dressed as a pilot (doncha just love a man in uniform?) Jason Statham went as Zorro, and Anthony Kiedis, Kate's brother Oliver Hudson and many many more came in costume.

Wonder what Kate dressed up as? A Tour de France cyclist is probably out of the question, right?

Check out the gallery below and tell us who would win in a costume contest!
