The American singer was dignified on stage as she returned to the city just weeks after the horrific terrorist attack at her concert at the Manchester Arena, which killed 22 people and injured 59 others.
With the help of her pop star friends and manager Scott Braun, Ariana pulled together a massive concert at Old Trafford cricket ground attended by 50,000 fans.
It also came two days after another devastating terrorist attack in London Bridge, which saw seven people killed after three men went on a rampage in the popular tourist spot.
But last night, the music world remained defiant and sent a powerful message of unity and peace to show that terrorism will never win as there’s too much love and kindness in the world to let hate prevail.
It was a message the world needed to hear, now more than ever.
