The "One Love" concert was dedicated to the 22 victims who were killed by a suicide bomber after Grande's May 22 "Dangerous Woman" tour performance wrapped up.
During the show, she revealed that she had changed the set list after meeting one of the terror attack victims' mothers.
Earlier on Sunday, Usher shared links to websites where fans could tune into a live stream on the event on his Twitter page. "Everyone getting back on their feet, I am so proud of you", she proclaimed.
Ariana Grande's star-studded One Love Manchester benefit concert proved to be a night of healing and joy, but one performer was noticeably absent from its lineup. Thank you so much for coming together and being so loving and strong and unified.
Ariana Grande and her crew got matching Manchester bee tattoos as a permanent tribute to the city following last month's terror attack at Manchester Arena. "The love that we have here is the medicine that we need right now".
The British Red Cross tweeted that 2.35 million GBP (or a whopping 3 million USD), had been accumulated throughout the performance, bringing the total to a staggering 12.4 million dollars.
The concert, which raised over $3 million, was held to raise money for the families of the 22 victims who died and almost 50 who were injured during the May 23 terror attack.
