The show, which took place on June 4, was organised as a charity event by the "Side To Side" songstress, in wake of the May 22 terrorist attack at the Manchester Arena.
Grande, 23, shared a lengthy thank you message on Instagram for her fans for "wiping her tears away".
"At the close of this European leg of my Dangerous Woman tour, I just wanted to thank you properly for the overwhelming love and support you've shown me, my crew, and each other during this challenging time.
She also shared a video snippet from the show, which was organised to raise funds for the victims.
Terror outfit ISIS claimed responsibility of the attack that claimed 22 lives and injured 59.
Grande will receive honorary citizenship of Manchester on July 12.
