Dita Von Teese will join the cast of “Sleep No More” for a special New Year’s Eve performance, sources say. The burlesque queen’s role is being kept under wraps. But word leaked that Von Teese was interested in joining the cast last month when she was overheard talking about the show at a Royalton event. Jude Law and Uma Thurman were spotted at the Chelsea show this week. The two hung out together at the theater’s Manderley bar, spies said.
