Artists Show Support for Ariana Grande's Manchester Benefit Concert on Twitter

Artist support for Ariana Grande's One Love Manchester benefit concert on Sunday (June 4) wasn't limited to those who were on the show's lineup. While acts like Justin Bieber, Miley Cyrus, Coldplay, Katy Perry, Niall Horan, Liam Gallagher and more performed -- and many took a few moments to share inspiring words live from the stage -- other peers gave Grande's event, which raised more than $3 million for the British Red Cross' Manchester Emergency Fund, a nod on social media.

"i'm sobbing watching #OneLoveManchester Im SO proud of @ArianaGrande and the other artists there, and Manchester for fighting fear with LOVE," Camila Cabello tweeted.

"So moved by #OneLoveManchester," Fifth Harmony said. "Unity and love are the most powerful forces in this world."

"So proud to see the perseverance of the people of #Manchester today and of all those who performed and participated tonight," Enrique Iglesias wrote.

Meanwhile, John Legend tweeted: "Thank you @ArianaGrande and all involved in putting this together."

Proceeds from the concert will benefit victims of the terror attack at Manchester Arena on May 22, as well as their families. The fund "will help alleviate immediate suffering and ensure victims and their families do not face short-term financial difficulties," the British Red Cross said on Twitter.
