at people comparing Beyonce's 4 night concert revue to Katy's 100+ dates tour.
You can tell how intelligent some people in this thread are.
Didn't the I Am tour out-gross the California Dreams tour?
Katy is way more successful on US iTunes, radio, her album sold more than 4, she even got more Grammy nominations. Her Grammy performance >> Beyonce's Grammy performance because having a Grammy performance > not having one!
Katy's fine, fresh, fierce, she got the charts on lock.
