Members of the “Glee” cast, including Lea Michele, Cory Monteith and Amber Riley are expected to perform on former “American Idol” judge Simon Cowell’s British talent show, “The X-Factor” on Dec. 5. The appearance will mark “Glee’s” first live performance outside of the United States, and serve as a primer for the cast’s just-announced European tour.
