Grande's manager Scooter Braun said on Sunday that the concert will go on as planned.
The album's proceeds will purportedly go to a charity benefiting the victims of last month's attack, which killed at least 22 people and wounded nearly 60 more.
A star-studded lineup including Justin Bieber, Coldplay, Katy Perry, Miley Cyrus, Marcus Mumford and Take That is scheduled to perform. "We ask at this time that we all continue to support the city of Manchester and all those families affected by this cowardice and senseless act of violence", according to a statement.
His eight-year-old daughter Hannah had left the Grande concert just before the deadly bombing and said she was "happy to be back" to see some of pop's biggest names. "Our way of life has once again been threatened but we will overcome this together". Following last month's terrorist attack at Ariana's gig at the Manchester Arena, people across the city got bee tattoos to show their solidarity with the victims.
Grande, who described herself as "broken" following the May 22 bombing, had immediately returned to the United States, interrupting her Dangerous Woman world tour and later promising to return for the charity concert.
In a night filled with emotional performances, and nearly endless singing from the crowd of 50,000, it was Grande's final song of the night "Somewhere Over The Rainbow" that brought most tears to the eyes.
The concert, which sold out with an attendance of around 50,000, raised over $3 million for the Manchester Emergency Fund.
If that wasn't enough, the 23-year old singer found another way of paying tribute to the victims and honouring Manchester.
Grande also ushered in artists like Little Mix and Imogen Heap, while Stevie Wonder was featured in a video segment where, while strumming his keyboard declared, "Love is truly the key, I don't care what ethnicity you are, what religion you are".
