Pollstar has just released their official Top 50 Worldwide Tours Ranking for the first half of 2012, with Lady Gaga leading on the female front. She ranks at #5 overall, without even landing in Europe/North America/South America yet!
The Born This Way Ball is on track to be one of the highest grossing tours of all time, and comes off of the highest selling American album of 2011, Born This Way. The album also produced three multi-platinum hit singles in the US.
The tour sold out every single show in its an Asian leg, a feat not reached by a Western act in years.
