Coldplay's Chris Martin performing in London during their 2008 winter tour
The Killers and Coldplay have announced plans to play a one-off charity gig.
The two bands are due to perform at Shepherds Bush Empire on 18 February for the War Child organisation.
Tickets for the double header are priced at £50 and will be available through a lottery system.
Fans can enter the lottery at 9am, on 30 January through the charity's website. The event will follow that evening's Brit Awards with both bands playing 45 minute sets.
In a statement, Coldplay said: "In our eyes, War Child is one of the world's most important charities, and The Killers are one of our favourite bands, so playing this concert is an absolute pleasure for us."
The Killers added: "Coldplay were one of the bands that gave us hope when we were just four boys in a garage. To share the stage with them for the War Child cause is an honour."
The concert is being held to celebrate War Child's 15th Anniversary and the release of their new album Heroes, which is out on 16 February.

Hot Chip, Duffy, TV On The Radio, Lily Allen and Elbow have all recorded tracks for the covers album.
The concept of the record involves legendary acts such as David Bowie choosing tracks from their back catalogue for current artists to sing.
Among the tracks slated to appear on the album are The Kook's cover of The Kinks track Victoria, Duffy's take on Live And Let Die and Elbow's cover of U2's Running To Stand Still.
All profits from the concert will go to aid War Child's work to protect the children in war zones.
The release comes four years after War Child's last album Help! A Day In The Life, which featured Radiohead, Coldplay and the Manic Street Preachers.
Former Stone Roses guitarist John Squire has also designed the cover for the new record after creating original artwork for the charity's debut album in 1995.
