BROOKLYN - Hundreds of people flocked to a random street corner in Williamsburg Wednesday afternoon to score free tickets to one of the hottest shows in town.

Singer Rihanna sent out a tweet promising fans tickets to The Global Citizen Festival if they could find the location pictured.

The biggest names in pop culture and politics will be on hand at the event.

The Global Citizen Festival will take place Sept. 24 at Central Park's Great Lawn.
