Ariana Grande wept for days after she found out that 22 of her fans had died when a terrorist let off a bomb at her concert in Manchester last year.
The 'One Last Time' hitmaker was left heartbroken last May when she was told that 22 people - many of whom were children - had died after an extremist let off an explosion outside Manchester Arena just minutes after she concluded her gig, which was part of her 'Dangerous Woman' tour.
Ariana's manager Scooter Braun said: "When she found out that fans of hers had died she was so sad. She cried for days, she felt everything - every face they announced, every name, she wore on her sleeve. Every bit of emotion because that's who she is."
The 24-year-old singer flew straight back to the US to come to terms with the incident with the help of her loved ones, but days later she was back in Manchester visiting her injured fans at the Royal Manchester Children's Hospital, which was the "hardest two hours" of her life.
Scooter added: "After the first family I had to help her, she was distraught and I was lost. It was beyond tough. But every single time we got down we reminded each other we get to go home. Our loved ones are still going to be there. That mother is never coming home, that daughter is never coming home, that son is never coming home, that dad is never coming home."
And, although she was devastated by the incident, Ariana and Scooter - who is also Justin Bieber's manager - decided to return to touring because they didn't have a "right" to be sad.
Speaking on the Big Questions with Cal Fussman podcast, Scooter, 36, explained: "We didn't have the right to be so sad we couldn't continue.
"The terrorist made a mistake ... they picked the wrong goddamn show. Because if they thought we were going to roll over they don't know Ariana and they don't know me."
Less than a month after the attack, Ariana returned to the British city to put on the One Love Manchester benefit concert, which raised money for the families affected by the tragedy.
