Sting is set to team up with No Doubt to help raise awareness about the world's poverty issues at the Global Citizen Festival this weekend (27-28Sep14).

The collaboration details are currently under wraps, but show producer Ken Ehrlich tells Billboard.com it was No Doubt's idea to pair up with the Roxanne hitmaker.

He says, "In this case, it was pretty organic. It came from No Doubt. We talked about a couple of possible people to do something with. As soon as we mentioned Sting, they loved that...

"(Sting) was very excited about doing it. His desire to do it was quick, but it really came down to making sure scheduling worked."

Jay Z will headline the charity festival, which will take place in New York's Central Park and will also feature performances from Carrie Underwood, the Roots and Tiesto.
