If somebody's interested (I remember somebody asked before), here is a comparison between Rihanna's ticket prices for Stade de France and Lady Gaga's ticket prices for the same venue, just so that you can imagine the final gross of the show if she really performed for 70k people tonight, considering how Gaga grossed over 6,3M from 70k people. Ok, so here are the real prices:
Rihanna
Pelouse (General Admission) - $79 for General Admission and $87 for Golden Circle
Carre Or (Golden Seats - close to the stage) - $123
Category 1 tickets - $109
Category 2 tickets - $94
Category 3 tickets - $65
Lady Gaga
Pelouse (General Admission) - $87 (she only had 1 price for the whole standing zone, no Golden Circle)
Carre Or (Golden Seats - close to the stage) - $158
Category 1 tickets - $130
Category 2 tickets - $94 (same as Rihanna)
Category 3 tickets - $65 (same as Rihanna, but more tickets available)
