Rap superstar Jay Z and rockers No Doubt have been tapped to headline the 2014 Global Citizen Festival.

The free concert will take place on 27 September (14) in New York City's Central Park and will be hosted by officials at the Global Poverty Project (Gpp), which aims to end extreme world poverty by 2030.

A statement from Jay Z reads, "Change only takes place when and where there is action. I'm joining the 2014 Global Citizen Festival because I believe through actions, whether it be by raising awareness, getting involved or educating ourselves, the goal to end extreme poverty by 2030 is possible."

No Doubt's Tony Kanal adds to RollingStone.com, "Global Citizen will be the first show No Doubt has played together in two years. It's a great way to get us back on stage. It was such an honour to be asked to play this particular concert. It's unacceptable that over one billion people live in extreme poverty, and it's got a pretty eclectic line-up, which reflects the event's true spirit of diversity."

The hitmakers will be joined by pop stars fun., country singer Carrie Underwood, hip-hop group The Roots and dance DJ Tiesto.

Tiesto says, "It's going to be an amazing show in one of the most unique venues in the world."
