AND that doesn't count her Australian leg which will gross 40M+ by the end of this year.
Not to mention she still has three more continents to visit next year.
The ARTGRAVE is over.
It will double the artGRAVE by the end of the year with just Australia + New Zealand per BB Boxscore.
By the end of the tour, it will have done over 200M. Beyond that we won't know until the venues for the Asian and South American dates are announced and the extent of these legs.
To put it simply, it's 2011 all over again except reversed and worse for the losing end (Gagz).
Katy remains the lowest-selling pop artist since 2008 (Lady Gaga, Taylor, Adele, Michael Bublé, Rihanna, Coldplay, P!nk, Beyst, 1D etc have sold way more albums in that timeframe)
