Kate Hudson held her annual Halloween bash at her home in LA on Friday night, and as usual, the event brought out her family members and famous friends. Katy Perry, Jessica Alba, and James Corden all arrived in costume, while the belle of the ball herself was decked out as a lady of the Wild West.

Kate gave fans a sneak peek at her party planning via Snapchat on Thursday. While hanging with her newly-single pal Jennifer Meyer, Kate walked viewers through the setup of her house and shared the recipe for the night's signature cocktail, a bloody cosmo. She also shared photos from the bash on Instagram, captioning one of herself and a friend, "Wild West got us like 💃@jonastahlin #SeeYouOnTheOtherSide."
