With countless amounts of faux lashes, body glitter and extravagant costumes, the new Broadway hit Priscilla Queen of the Musical already boasts a pretty high camp level, but the backstage atmosphere got even more wild when the cast welcomed two special guests on May 9. Dynasty diva Joan Collins (a Broadway veteran herself thanks to a 1992 revival of Private Lives) and her author sister Jackie Collins headed over to the Palace Theatre to boogie with the drag queens of Priscilla. After the performance, the Collins girls snapped a shot with show stars Tony Sheldon, Will Swenson and Nick Adams and others cast. Take a look at these glam shots, and be sure to plan your own visit to Priscilla!
