Guests at last night's party celebrating the launch of the new issue of VMAN got a preview of the new Mondrian SoHo, which is as yet unopened. Kanye West joined friends and supporters (among them Harley Viera-Newton, Leigh Lezark, Sky Ferreira, Richard Chai, Prabal Gurung, Evan Lysacek, Vera Wang, Andres Santo Domingo, Kehinde Wiley, and Chromeo) at the event—and all were surprised when, to the sounds of Rihanna's "Umbrella," a shower of drink tickets and dollar bills rained from the ceiling.
