On Tuesday (Aug. 7), the Global Citizen Festival announced its star-studded lineup for the free ticketed event, featuring performances by Janet Jackson, The Weeknd, Shawn Mendes and more.

The festival, which is an annual event organized by Global Citizen, is dedicated to promoting advocacy. Anyone can win tickets to the event by downloading the Global Citizen app, which allows one to earn points in exchange for acts of advocacy. Whether it’s sending a tweet that spreads awareness about one of the organization’s causes -- which range from ending global poverty to education equality -- or making a phone call to people in positions of power asking for a change, each of the actions is about using one’s voice to make a change rather than their wallet.

This year’s fest will be hosted by the husband and wife duo Deborra-lee Furness and Hugh Jackman. There will also be performances and/or appearances by Cardi B, Janelle Monáe and John Legend.

The Global Citizen Festival will be held on the Great Lawn in New York City's Central Park on Sept. 29.
