Selena Gomez, Olivia Wilde and More Fight Poverty at Global Citizen Festival

What do you get when you put Selena Gomez, the Foo Fighters and 60,000 people together in New York's Central Park? - The Global Citizen Festival.

Movie stars, rock stars and Victoria's Secret models put their fame to good use Saturday night for the largest syndicated live stream in history intended to raise awareness for eradicating extreme poverty. Millions watched it live streamed on YouTube, VEVO and several other outlets.

Festival co-founder 29-year-old Hugh Evans said the concert was purposely scheduled at the same time as the UN General Assembly in New York, so that they could get their message out to world leaders.
