Britney Spears' “Circus” won't be coming to Warsaw. The singer, whose hits include “...Baby One More Time” and “I'm a Slave 4 U,” has been playing a series of shows this summer in Europe, including in Britain, France and Sweden. The July 24 show in Warsaw was canceled because of a contractual dispute that could not be resolved, a statement released by her publicist said Wednesday. Phone calls to the concert organizer in Warsaw, Agencja Akwarium, went unanswered. The Warsaw concert was to have been Spears' second-to-last show in Europe before the “Circus” tour returns to the United States. She is scheduled to play at the 02 Arena in the German capital, Berlin, on July 26.
