One Love Manchester was a benefit concert and British television special held on 4 June 2017, which was organised by 23 year old American singer Ariana Grande in response to the bombing after her concert at Manchester Arena two weeks earlier.
The concert took place at Old Trafford Cricket Ground in Old Trafford, Greater Manchester, and aired live on BBC One in the UK with hosts Sara Cox and Ore Oduba. The concert was attended by 50,000 people.
Guest stars included Justin Bieber, the Black Eyed Peas, Coldplay, Miley Cyrus, Marcus Mumford, Niall Horan, Little Mix, Katy Perry, Take That, Imogen Heap, Pharrell Williams, Robbie Williams, and Liam Gallagher.
Proceeds from the event benefit the We Love Manchester Emergency Fund, which was established by the Manchester City Council and the British Red Cross following the 22 May bombing, which killed 22 concert goers and injured more than 100.
