Rachel and Kurt have long venerated Patti LuPone on Glee, and now they're about to come face to face with her. TV Line reports that while the show films in New York for its season-ending episodes, the two characters will run into LuPone (playing herself) at Sardi's. Will more Glee characters meet their idols next season? Perhaps Mercedes can sit down with Aretha Franklin, or Mr. Schue can meet trailblazing white rapper Snow? UPDATE: We're hearing that the scene will actually involve Rachel and Finn, not Kurt. Someone is going to be jealous. [TV Line]
