This is the third installment of the annual charity event, which aims to bring awareness to worldwide poverty. Other performers include Carrie Underwood, fun., The Roots, and DJ Tiësto. Of course, this star-studded lineup is going to cost you: VIP admission ranges from $100 to $675.
But, shelling out the big bucks is not the only way you can get to see Hova and Gwen hit the stage. The Global Poverty Project will be distributing 24,000 pairs of tickets for free. To qualify for the lottery, you must perform community service and engage in social-media activism for a number of causes. That's a pretty reasonable price tag to see all of these stars live.
