Ariana Grande surprised injured fans hospitalized from the terror attack at her Manchester concert last week.

"This means more to us than all the amazing things people have done this week," Peter Mann shared on Facebook along with photos of 10-year-old victim Jaden Farrell-Mann with the singer. "When your daughter asks after her 2nd operation is ariana ok? so happy she came i could burst! Never seen jaden so happy! even cried again myself."

Grande visited Farrell-Mann and other young fans still recovering at the Royal Manchester Children's Hospital Friday night.

The singer will be joined by Justin Bieber, Katy Perry, Pharell Williams and more on Sunday during a charity concert to honor the victims of the attack.

The "One Love Manchester" show will be held at the city's Old Trafford Cricket Ground, almost two weeks after a suicide bomber detonated an improvised explosive device at the Manchester Arena, killing 22 people and injuring 116.

According to BBC News, Take That, One Direction's Niall Horan, Miley Cyrus, Usher and Coldplay will also perform at the benefit concert. Those who attended Grande's original concert will receive free tickets.

Freeform will air the full concert live at 2 p.m. ET, while ABC will air a one-hour highlight special following its NBA Finals game later that same evening. Freeform will also air the benefit on their app. A host of other networks will carry the concert event, which is being produced by the BBC, for viewing outside of the United States.

Grande announced she would be returning to Manchester for the concert four days after the attack, writing, "our response to this violence must be to come together, to help each other, to love more, to sing louder and to live more kindly and generously than we did before."

Grande's "Dangerous Woman" tour was postponed Wednesday in response to the attack.

Salman Abedi, a 22-year-old U.K.-born man of Libyan descent, detonated a homemade bomb following the concert on May 22. It marks the worst terrorist attack in the U.K. since the London bombings on July 7, 2005, that claimed 52 lives.
