FireAid, a benefit concert to raise money for relief efforts in the Los Angeles fires, will take place on 30 January.
A whole host of stars have been confirmed to perform at the event.
These include Billie Eilish, Green Day, Gwen Stefani, Lady Gaga, Jelly Roll, Katy Perry, Joni Mitchell, P!nk, Red Hot Chili Peppers, Rod Stewart, Sting, Stevie Nicks, Earth, Wind & Fire and Gracie Abrams.
More names are due to be announced.
It's also believed U2 is in discussions about performing, although this is not yet confirmed.
The Eagles have already donated $2.5 million (£2.04 million) towards the event, although it is unclear if they will also be performing.
The concert will take place at the end of the month. Performances will happen at a new indoor arena in Inglewood, the Intuit Dome, and the nearby Kia Forum, a longtime landmark. Both shows will take place simultaneously.
Tickets for the fundraiser will go on sale on 22 January.
The show will also be streamed live on a range of platforms including Apple Music, Apple TV, Paramount+, Prime Video and Spotify.
Money raised from FireAid will be given to both short-term relief efforts and long-term initiatives to prevent future fire disasters. There will be a focus on using the funds to "rebuild infrastructure, support displaced families and advance fire prevention technologies and strategies."
The shows will take place three days before the 67th annual Grammy Awards is due to happen.
