From Charlie Sheen to Lindsay Lohan, comic genius Kathy Griffin takes plenty of shots at famous folks in her new Broadway show, Kathy Griffin Wants a Tony. Yet despite her Hollywood badmouthing, some celebrities are fans of Griffin's acidic wit, including Broadway veteran Rosie O'Donnell. During the show's March 14 performance, Griffin invited O'Donnell on stage at the Belasco Theatre to help celebrate her Broadway debut. The duo continued to bond even after the curtain went down as Griffin joined O'Donnell to watch Sister Wives and The Celebrity Apprentice. O'Donnell even took to Twitter to frequently express her reactions throughout the broadcasts. Don't miss your chance to catch Griffin live on Broadway through March 19!
