Ariana Grande returned to Manchester on Sunday night for a benefit concert, less than two weeks after a suicide bomb killed 22 people at her Manchester Arena concert on May 22.
The star-studded One Love Manchester show also included performances from Justin Bieber, Coldplay, Take That, Mumford and Sons, Robbie Williams, Little Mix, and Katy Perry.

The One Love Manchester benefit concert for the victims of the Manchester Arena terror attack was held at the Old Trafford cricket ground in Manchester, which has a capacity of around 50,000.
Ariana Grande had offered free tickets to those who were at her Manchester Arena concert on May 22.
The concert is expected to have raised more than £2 million for victims of the attack in just three hours.
All proceeds are going towards the We Love Manchester emergency fund, set up by Manchester City Council and Red Cross. The total collected by the fund is now over £10 million, according to The Independent.
Mike Adamson of The Red Cross told the Associated Press: “We expect to raise another one and half million pounds from ticket sales tonight and then further funding from the TV rights and merchandising.”
The tribute concert took place one day after a terror attack in London that killed 7 people and injured 48.
Armed police guarded the venue.
However, that didn’t stop the excited crowds from flocking in.
The atmosphere softened throughout the evening. Here, concertgoers take a selfie with the armed police.
Policemen were even seen dancing with the crowd.

Among the messages seen in the crowd were signs saying: "We Stand Together."
And the show didn't disappoint. Former Oasis frontman Liam Gallagher performed "Live Forever" with Coldplay's Chris Martin.
Martin was back with Coldplay, who moved the crowd with "Fix You" at sunset.

Little Mix's performance of "Wings" was about encouraging people to "stand together and not let anything bring them down," according to the band.
"No matter what you say it won't hurt me/Don't matter if I fall from the sky/These wings are made to fly," the lyrics read.
Katy Perry told the crowd: "Love conquers fear and love conquers hate and this love that you choose will give you strength, and it's our greatest power."
