The Ariana Grande tribute concert has well and truly kicked off, with a plethora of stars performing their biggest hits for the crowd.

One of the biggest moments so far was when Ariana told the crowd about meeting 15-year-old Olivia Campbell’s mum last week.

Olivia was murdered during the Manchester terrorist attack and Ariana dedicated her hit, ‘Side to Side’ to the teen.

She said, ‘I had the pleasure of meeting Olivia’s mummy a few days ago and as soon as I met her I started crying and I have her a big hug. And she said that, ‘I should stop crying because Olivia wouldn’t of wanted me to cry.’

‘And then she told me that Olivia would have wanted to hear the hits.’

And the hits, she played.
