Hot supermodel Anja Rubik, who walked in Paris and Milan and has graced the covers of numerous fashion magazines, will host a Stoli-sponsored Halloween party with Kanye West at The Darby tonight. The supper club will be transformed into a gypsy-themed bash with belly dancers and tarot card readers for the beautiful group. Sources say the Polish model has been involved in all of the planning and preparation — from the theme to the performance and the guest list.
