The singer performed "One Last Time" during her set at Manchester Arena on May 22, the location of the terror attack that took the lives of nearly two dozen people and injured many more.
This weekend, the "Dangerous Woman" singer is holding her One Love Manchester benefit concert to honor and help those who have been affected by this heartbreaking event, and she's also chose to spread some cheer to her fans who won't be able to make it to the show.
The attack at Manchester Arena following the singer's concert on May 22 left 22 people dead and dozens injured, many of them children who had come to see their favourite singer perform.
She sat at the bedside of children at the Royal Manchester Children's Hospital who are still recovering from the suicide bombing. Grande also brought each injured fan a sunflower and a teddy bear, CNN reported.
Twenty-two people died at the show and more than 100 others were injured.
She surprised her fans at a hospital in Manchester ahead of the benefit concert on Sunday.
Ariana Grande was spotted at Stansted Airport on Friday with her parents and boyfriend, Mac Miller.
One Love Manchester will also air in countries including Brazil, Germany, China, Australia, Italy, Mexico and Sweden with more deals still being made.
