Lady Gaga is ambitious. We know this already, since she scratched and clawed her way out of the Lower East Side to ascend into the pop stratosphere, breaking a lot of dagger-shaped nails in the process. But now she’s riding high and is the biggest pop star on earth. That’s why the rumor that she is planning a record-breaking, 450-date global tour doesn’t shock us! It’s typical of Gaga to plan a tour that’s bigger than the towering stiletto heels she is known for wearing.
