Olivia Rodrigo and Stevie Wonder join FireAid line-up

Olivia Rodrigo and Stevie Wonder are among the latest acts to join the line-up at the upcoming FireAid concert.

The pair have agreed to perform at the double-venue event - scheduled to take place in Los Angeles on January 30 - to raise funds for victims of the California wildfires.

The fires have killed at least 27 people and destroyed thousands of buildings across the state.

Other stars to join the bill include Alanis Morissette, John Fogerty, the Black Crowes and Graham Nash as well as previously announced artists Lady Gaga, Billie Eilish, Stevie Nicks, Katy Perry and Sting.

Gwen Stefani was previously listed as performing, but it has since been confirmed she will be reuniting with her band No Doubt for the event following a decade-long hiatus.

A message posted on the concert's official Instagram page previously teased: "Two venues. One night. Your favorite artists coming together for music and solidarity.

"Shows start at 6pm. Tickets go on sale January 22nd at noon PST ... Contributions made to FireAid ... will be distributed under the advisement of the Annenberg Foundation and will be distributed for short-term relief efforts and long term initiatives to prevent future fire disasters throughout California."

The concert has been described as an "evening of music and solidarity" to raise vital funds to help communities devastated by the fires.

It will be broadcast and streamed on services including Apple Music and Apple TV, iHeartRadio, Netflix/Tudom, Paramount+, Prime Video, SiriusXM, YouTube and more as well as being shown at a number of cinemas across the US.

The LA Clippers will cover all expenses associated with the event, so all proceeds can go towards rebuilding communities and looking at preventative measures to help halt future disasters.
