Friday night, some of Hollywood’s biggest stars got all decked out in their spookiest finery to attend Kate Hudson’s annual Halloween party. There were some pretty excellent costumes, be them princessy or, well, downright scary.
Check out some of our favorites after the jump.
(At left is Rashida Jones, of Parks and Recreation, as a blow pop — one of our favorites of the night.) Gwen Stefani went all out with the princess get-up. 
Nikki Hilton, meanwhile, did a demure Little Red Riding Hood. 
While Jessica Alba got witchy. 
Did you see any other good ones? Let us know — and happy Halloween!
