Patti LuPone is one of Broadway's biggest divas, and during a Jan. 10, 2009, performance of "Gypsy," she proved it. Patti was in the middle of performing "Rose's Turn" when she saw a man taking photos with a flash -- a major theater no-no -- so she stopped the show and demanded that the offender be thrown out. "You heard the announcement in the beginning, you heard the announcement at intermission!" she screamed. "Who do you think you are?" What do you think Patti would have done to the sneaky person who videotaped the whole outburst -- and put it on YouTube?
