But being the brave chick that she is, Ari immediately sprung to action to help those affected by the attack.
From the emotional One Love concert to visiting the injured victims, the pop icon has been determined to make a difference.
And now, she has done something to keep the victims with her forever.
The Sun has reported that the 23-year-old and her crew got matching tattoos of a bee, Manchester's mascot.
Ari and her Dangerous Woman Tour fam were met backstage by tattoo artists who inked the band just after the concert ended.
Hundreds of other peeps got the same bee tatt as part of a fundraiser to raise money for the victims.
The British Red Cross claim to have received $3 million during the One Love Manchester broadcast, and over $13 million dollars in the following 12 hours.
