Rumors that have grown to almost a certainty know are that the Queen of Pop's Sticky & Sweet tour is going to be extended this summer.
Different sources are reporting that Madge and her team are planning to add some cities that weren't on the tour last year to their upcoming schedule. And, no, it won't be a new tour, just an extension of the shows last year. Currently the new extension will last for two months, all of July and August.
At the moment, we're only hearing of European cities being added. Nothing has been confirmed 100% just yet, but by the looks of things and from what we're hearing, it looks like it's definitely going to happen.
