Billboard reports that 25 more shows for Madonna's Sticky & Sweet tour have been added, and the first stop will be at the O2 Stadium in London on July 4.

"This is a first for me. I've never extended a tour before. I'm excited to be going back on the road, visiting places I've never been and returning to places I love," said the 50-year-old star.

Her tour is the highest earning tour of all time for a female artist, breaking several records in terms of ticket sales.

So far, 2,350,285 spectators have seen her Sticky & Sweet show, which has hit 58 cities. The complete list of concerts can be found on Madonna's Website.
