Michael Kors will be feted in Tokyo next month with a special performance by Jennifer Hudson at the residence of US Ambassador John Roos, we’re told. Kors will be there to celebrate the opening of his new Roppongi Hills store, and the “Project Runway” star will debut a limited -edition Hamilton handbag and leather goods collection with all proceeds going to the Japanese Red Cross Society. The party and opening will coincide with Tokyo Fashion’s Night Out on Nov. 5.
