Everyone wants to lend a helping hand.

Ariana Grande's Manchester benefit concert this Sunday will feature a handful of huge acts, including Justin Bieber, Katy Perry, Miley Cyrus, and Coldplay to name a few, TMZ reports. Others include Niall Horan, Pharrell, and Take That.

The singer will headline the event at Old Trafford cricket ground just two weeks after the horrific terror attack at her concert at Manchester arena. All the proceeds will go to the victims' families.

No doubt security will be insane for this.
