Ariana Grande has put together a huge benefit concert for the victims of the Manchester terror attack, and it will be held THIS Sunday.
The star-studded lineup includes Justin Bieber, Coldplay, Katy Perry, Miley Cyrus, Pharrell, Niall Horan, Usher, Black Eyed Peas, and British group, Take That.
Tickets officially go on sale tomorrow, and Ariana is offering free admission to fans that were at her Manchester show last week.
Obviously security will be very tight; concertgoers are being asked to not even bring bags with them to the event.
