Kate Hudson threw her annual Halloween party in LA on Saturday night, and as usual the guest list was lengthy. The crew got all decked out, from Cindy Crawford dressed up as Amy Winehouse to Tobey Maguire and Jennifer Meyer as a white trash couple. Courteney Cox and David Arquette were a witch and a warlock — couples costumes were pretty popular. The hostess of the evening was dressed, appropriately, as an airline flight attendant, there to keep everyone full of beverages all night long. Things even got a little out of hand, and the cops had to stop by to tell them to quiet down. There were no celebrity babies allowed at this adults only party, but we'll get to see them all dressed up for trick or treating at the end of the week.
