Having shaken those tagalong Gorillaz, Madonna uncorked very big news on Thursday's The Ellen DeGeneres Show. "OK, are you guys ready? I can't hide it anymore I'm going on tour this summer," the Material Woman announced to the studio audience. No details came forth, but the buzz is that any new stage show would focus on her latest Confessions on a Dance Floor disc. "Her last tour was kind of a 'greatest hits' tour, and I don't think she would want to repeat all the songs," Madge's rep, Liz Rosenberg, recently told Rolling Stone. "But there are a few off the list that she left out." Ooh, like "Jimmy Jimmy"?!
