Carrie Underwood Announced as Headliner for Global Citizen Festival

Carrie Underwood will co-headline a free concert at Central Park on September 27, and it's all for a good cause.

The songstress is performing for the Global Citizen Festival as part of the Global Citizen Movement, which is continuing its campaign to eradicate extreme poverty all over the world by 2030.

"I believe we all have the ability to make our world a better place," Underwood says. "Positive change is possible when we work together, and this festival is a hopeful opportunity for all of us to help see an end to extreme poverty."

Other headliners include Jay-Z, No Doubt, fun, the Roots and Tiësto. Citi is partnering with the Global Citizen Festival, giving card members exclusive access to VIP offers.

“The Global Citizen Festival brings together a stellar lineup to support an immensely important cause, at an iconic venue in Central Park,” Jennifer Breithaupt, SVP of Entertainment Marketing at Citi, says. “We are honored to sponsor again for the third year, to be the presenting partner of the VIP tent and offer our card members VIP access to what will certainly be an impactful and memorable event.”

The Global Citizen Festival, now in its third year, coincides with the UN General Assembly. In addition to the powerful performances, the event will also serve as a platform for commitments from global leaders to become pro-active in the areas of vaccines, education and sanitation.

Free tickets are now available by participating in online actions at www.globalcitizenfestival.com. Users can complete several different actions to earn their admission, including signing petitions and learning more about immunizations.

The concert will air live on MSNBC, with NBC News also hosting a one-hour prime time special about the event at a later date. More information about the Global Citizen Movement is available here.
