9 Most Powerful Moments From Ariana Grande's One Love Manchester Benefit Concert (Video)

The benefit concert comes just two weeks after a terrorist attack at Grande's Manchester "Dangerous Woman" show left 22 concertgoers dead and over 100 injured. The singer vowed to stay strong, sharing that she would return to the "incredibly brave city" for a special performance. All proceeds from the concert will go directly to the We Love Manchester Emergency Fund.

From special duets to tearjerking tributes to the people of Manchester, keep reading for 9 of the most unforgettable moments from the show:

Before bringing out Cyrus to perform "Happy" with him, Williams honored the crowd saying, "I'm bowing because despite all of the things that have been going on in this place, I don't feel or smell of hear or see any fear in this building. All we feel tonight is love, resilience, and positivity."

Before she graced the stage, Grande's manager Scooter Braun appeared in front of the audience for a dedication to the victims who lost their lives at Ariana's Manchester two weeks ago. He also commended the singer for being the "bravest person he knows."

"Hatred will never win, fear will never divide us, because on this day, we all stood with Manchester," he said.

The Black Eyed Peas were joined by Grande for a special version of their hit "Where Is The Love," dedicated to the city of Manchester.

A very emotional Grande joined Parrs Wood High School Choir to sing her hit, "You Are My Everything." The singer was obviously stricken by emotion during the performance, embracing the choir and praising the young talent in the beautiful rendition of her song.

Cyrus returned to the stage hand-in-hand to perform a cover of Crowded House hit, "Don't Dream It's Over." Before the performance, Cyrus praised her friend Ariana, admiring her for the incredible show she put on saying, "You've always been there for me, I'm happy to be here for you."

The singer completely brought the house down when he appeared on stage with just a guitar. Bieber performed acoustic versions of his hits, "Love Yourself" and "Cold Water". Bieber too, praised the audience and Grande for the concert saying, "would you agree that love always wins?" He later asked the audience to join him in a "love" chant. Before leaving the stage, the singer tearfully praised those who lost their lives in the tragedy saying, "To the families, we love you so much" and "God is good in the midst of the darkness."

Before surprising the audience by bringing out Manchester native and former Oasis band member Liam Gallagher to end the evening, Grande joined Coldplay on stage to sing "Don't Look Back In Anger." The Oasis song was one crowds in Manchester sang during a vigil for the victims.

The Manchester native took the stage with Coldplay's Chris Martin to perform Oasis' hit "Live Forever."

To end the night, Grande gathered all of the night's performers on stage to join her in singing her hit, "One Last Time." A very emotional Grande was met with cheers from the audience, and her fellow performers including Miley Cyrus, Naill Horan, Katy Perry and Imogen Heap.

Grande then concluded the show with her own rendition of "Somewhere Over The Rainbow."
