The Black Eyed Peas and Robbie Williams will join Ariana Grande, Justin Bieber and other stars at a charity concert on Sunday in Manchester, England.

Live Nation said Thursday that girl group Little Mix has also been added to the show being held in honor of the Manchester bombing that took place at Grande’s concert in the city last week. Twenty-two people died at the show.

Katy Perry, Coldplay, Miley Cyrus, Pharrell Williams, Take That and Niall Horan also will perform. The event, dubbed One Love Manchester, will take place at Emirates Old Trafford.

Tickets went on sale on Thursday. Proceeds will go to an emergency fund set up by the city of Manchester and the British Red Cross.
