Justin Timberlake, Sir Elton John and Katy Perry are among the A-list performers set for this year's iHeartRadio music festival in Las Vegas.
Ryan Seacrest will host the event, organiser Clear Channel announced. Tickets for the third annual festival go on sale on July 20.
"We try to cover every genre our stations play with the line-up," said Tom Poleman of Clear Channel. "Someone like Elton John has been an icon on our radio stations for years, and for him to the take the stage alongside people like Justin Timberlake and Katy Perry I think really speaks to what makes the festival unique."
The festival will air live across Clear Channel's radio stations and as a two-night special on the CW Network on September 30-October 1.
