DIVA ALERT: Patti LuPone to guest on season finale of “Glee”!

From Entertainment Weekly: The cast of Glee are currently shooting the season finale in New York City and hitting various Big Apple landmarks like Tiffany’s and Times Square.

So it’s natural for them to run into one of New York (and Broadway’s) biggest icons: Patti LuPone.

EW has learned Lea Michele (Rachel) and Cory Monteith (Finn) will share the screen with the fabulous LuPone. Fingers crossed for a sing-off between diva one (Michele) and diva two (LuPone)!
