That's average if anything considering she's been out for 18 years.
For example:
- When Rihanna was 8 years into her career (2013), she did $150 million+ on tour.
- When Beyonce was 10 years into her career, she was grossing $90 million on tour.
Cause touring is bigger now and Gaga and Katy are also not as long in the game and are also pulling 200 million grossing tours.
