Selena Gomez wears her Unicef tee proud as she attends the 2012 Global Citizen Festival held in Central Park, New York City on Saturday afternoon (September 29).

The 20-year-old Unicef Ambassador was joined by Minka Kelly, Sophia Bush, Olivia Wilde, Katharine McPhee and more for the all star concert featuring The Black Eyed Peas, Band of Horses and Foo Fighters.

“This advocacy concert will celebrate the progress already made in fighting extreme poverty, secure financial commitments for tackling extreme poverty and disease, and mobilise thousands of ambassadors for change,” the site continued. “We’ll unite around a simple yet powerful idea: that by giving every child a chance to thrive, our generation can end extreme poverty,” the Global Citizen website reads.
