Glee got a diva dose on its May 24 season finale, thanks to a guest appearance from two-time Tony winner (and nominee again this year) Patti LuPone. During the glee club's New York City adventure, Finn (Cory Monteith) tried to win back his ex-girlfriend Rachel (Lea Michele) with a romantic night on the town. While dining at iconic theater hangout Sardi's, the duo spotted LuPone (playing herself) at a nearby table. Rachel couldn't pass up the chance to meet one of her idols (she performed the Evita classic "Don't Cry For Me Argentina" on the show earlier this season), so she excitedly greeted the legendary leading lady. Humbled by Rachel's enthusiasm, LuPone delivered an inspirational message to the aspiring actress. Take a look at what she had to say below!
