Justin Bieber, Coldplay and Katy Perry will be among the artists joining Ariana Grande for a concert in Manchester, England, on Sunday that will raise money to help victims of the deadly attack May 22 that followed a concert by Grande.
Grande said Tuesday the One Love Manchester show will be at Old Trafford cricket ground.
Other performers will include Pharrell Williams, Miley Cyrus, Usher, Niall Horan and Take That.
Tickets go on sale Thursday. Proceeds will go to an emergency fund set up by the City of Manchester and the British Red Cross.
Following Grande's show earlier this month, a suicide bombing left 22 people dead and dozens wounded.
"We will not quit or operate in fear. We won't let this divide us. We won't let hate win," Grande said in a statement. "Our response to this violence must be to come closer together, to help each other, to love more, to sing louder and to live more kindly and generously than we did before."
The American singer added: "Music is meant to heal us, to bring us together, to make us happy. So that is what it will continue to do for us."
