Set to take place on Sunday 4 June at the Emirates Old Trafford cricket ground, less than two weeks after the atrocity, the event will see stars including Justin Bieber, Coldplay, Katy Perry, Take That, Miley Cyrus, Usher, Pharrell Williams and One Direction’s Niall Horan perform at the 50,000 capacity venue.
Tickets are being offered for free to those who were at Grande’s concert on the night of the attack and the show will be broadcast live on BBC TV and radio.
Any proceeds from the event will go to the We Love Manchester emergency fund.
The attack left 22 people dead – and a further 119 people injured - when a suicide bomber detonated a home-made bomb in the foyer of the Manchester Arena as concert-goers were leaving after Grande’s performance. The youngest victim was just eight years old.
Grande was “broken" over the events and suspended her tour but promised to return to Manchester “to spend time with [her] fans and to have a benefit concert in honour of and to raise money for the victims and their families”.
In an open letter published last Friday, Grande said “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.”
