Cardi B may have decided not to tour with Bruno Mars so she can recover from childbirth and focus on being a new mom, following the birth of her daughter Kulture on July 11th, but she will be performing next month in New York City. She was announced as one of the headliners of the 2018 Global Citizen Festival, along with Janet Jackson, The Weeknd, Shawn Mendes, and Janelle Monáe.

John Legend is also on the lineup, billed as the "special guest," and Hugh Jackman and Deborra-lee Furness are co-hosting. Other co-hosts include Camren Bicondova, Cynthia Erivo, Danai Gurira, Forest Whitaker, Gus Kenworthy, Kal Penn, La La Anthony, Naomi Campbell, Rachel Brosnahan.

The event, which advocates for a number of causes, from education and the environment to health and issues related to girls and women, will be held on September 29th in Central Park.

According to a press release, this year's festival has these specific goals: "Calling on Congress to resist the White House’s proposed cuts of 32% to American aid programs, which would devastate the fight against extreme poverty; Calling on the G7 countries to contribute to the $2 billion needed to tackle the world’s maternal health crisis that sees more than 5 million mothers and children die of preventable conditions every year; Ending the criminalization of poverty, through eliminating and drastically reducing the use of cash bail in jurisdictions including New York State."

At least year's Global Citizen Festival, Stevie Wonder took a knee "for America... But not just one knee. Both knees, in prayer for our planet, our future, our leaders of the world and our globe."

The event is free, but attendees have to "earn" tickets by taking certain actions. (MSNBC will air a live simulcast on the network and online.)
