Ariana Grande is returning to Manchester on Sunday, a week after a terror attack outside her concert killed 22 people and injured nearly 60 others.
The pop star will be joined by Coldplay, Miley Cyrus, Niall Horan, Katy Perry, Usher, Take That, and Canada’s Justin Bieber at a benefit concert called One Love Manchester.
Bieber will fly in after a Purpose Tour stop in the Netherlands on Saturday and fly out in time for his show in Denmark on Monday.
Grande, Bieber and Usher are all managed by Scooter Braun, who tweeted on Tuesday: "We stand with you."
In the hours after the bombing, Cyrus shared on social media that she wished she could "give my friend @arianagrande a great big hug right now" and offered "condolences to anyone and everyone affected by this horrific attack!"
British boy band Take That were scheduled to perform three concerts at Manchester Arena between May 25 and 27 but, following the tragedy, postponed the shows. Instead, they will do one concert on June 18 at Manchester's Etihad Stadium.
Although fans who were at Grande’s May 22 concert at Manchester Arena will receive free tickets to Sunday's benefit, proceeds from the sale of other tickets will support victims and their families. Organizers hope to raise about $3.5 million CAD.
The all-star concert is being held at the 50,000-capacity Old Trafford Cricket Ground.
“I'll be returning to the incredibly brave city of Manchester to spend time with my fans and to have a benefit concert in honour and raise money for the victims and their families,” Grande had promised in a Twitter message several days after the bombing.

A Greater Manchester Police spokesperson told BBC Radio that some familiar of the victims are not pleased with the idea of a benefit concert. “That is absolutely understandable,” said chief constable Ian Hopkins.
There are still 17 victims in critical condition in hospital.
Security is expected to be tight and concertgoers will not be permitted to bring bags to the event.
