She needs time to heal and mourn the tragedy.

Ariana Grande has canceled her concerts up until at least June 5 and maybe longer, TMZ reports. Her team is busy trying to assess how to handle security concerns in the wake of the terrorist attack at her show in Manchester on Monday night.

"The Dangerous Woman tour with Ariana Grande has been suspended until we can further assess the situation and pay our proper respects to those lost," Grande's management team confirmed to the outlet.

"The London O2 shows this week have been cancelled as well as all shows thru June 5 in Switzerland. We ask at this time that we all continue to support the city of Manchester and all those families affected by this cowardice and senseless act of violence. Our way of life has once again been threatened but we will overcome this together. Thank you," the statement continued.

Concert promoter Live Nation is aware of the safety concerns surrounding upcoming concerts in England, and will be issuing refunds to those too scared to attend. Katy Perry, Iron Maiden, KISS, Waka Flocka Flame, Robbie Williams, Phil Collins, Depeche Mode, and James Arthur are just a few of the acts scheduled in the next few weeks.

With the terror alert in the UK raised to critical, and Prime Minister Theresa May saying another attack seems "imminent," it seems like a wise move.
