Ariana Grande has confirmed she'll host a special concert in Manchester this Sunday to remember the victims of last week's attack.
The star has asked acts including Justin Bieber, Coldplay, Katy Perry, Miley Cyrus and Niall Horan to perform.
The One Love Manchester concert is taking place at Old Trafford Cricket Ground.
Twenty-two people died in an attack after her show last Monday in Manchester Arena.
Ariana is offering fans who were at the show free tickets.
