Justin Timberlake, Bruno Mars and Katy Perry are among the names confirmed for the iHeartRadio Music Festival at the MGM Grand Arena in Las Vegas in September. The two-day festival, set to be held on September 20 and 21, will also feature performances from Elton John, Keith Urban and a special pairing of Queen (with Brian May) and the former American Idol star Adam Lambert.

The main festival line-up was announced on Monday morning (July 15, 2013) in a press conference hosted by Ryan Seacrest. A final schedule will be announced closer to the festival, though Timberlake, Perry, Elton and Bruno Mars are likely to be the marquee names. The likes of Muse, Tiesto, Chris Brown, Fun, Phoenix, Maroon 5, Tim Mcgraw, Ke&ha, Thirty Seconds to Mars and Benny Benassi are other high profile names to have been confirmed. 

Last year's festivals played host to No Doubt, Pink, Usher and Swedish House Mafia though it will be remembered for Billie Joe Armstrong's meltdown during Green Day's set. After smashing the band's instruments in protest of his set being cut short, Armstrong left the stage and was admitted to rehab the next day, cancelling his band's tour dates and promotional appearances. 

For the first time, this year's festival features a special 'fan village,' complete with its own stages that will feature performances from Miley Cyrus, Avril Lavigne, Pete Tong and Twenty One Pilots.
