There was a feature about this in last month's issue of Q Magazine.
If I recall correctly, I *think* she's getting about 10% of ticket sales. The rest goes on stuff like hiring the venues, promotional material, shipping, dancers, the band etc etc.
Also, I think that figure is ticket sales - she'll also pocket a percentage of merchanise.
All in all, she should be looking at about �20-25million.
And she deserves every penny (I mean that - I'm going to see the show next Thursday).
