LOS ANGELES (TheWrap) - Lady Gaga, Coldplay, Bruno Mars and Nicki Minaj are among a slew of performers who will swarm on Las Vegas in September for the inaugural iHeartRadio Music Festival, Ryan Seacrest announced on Monday.
Seacrest will host the event, which is being produced by radio giant Clear Channel.
As might be expected from an event being hosted by Seacrest, there'll be a heavy "American Idol" factor to the proceedings, with current "Idol" judges Steven Tyler and Jennifer Lopez among the performers, along with former "Idol" competitors Carrie Underwood and Kelly Clarkson.
Seacrest called the upcoming festival, which will be held on September 23 and 24, a "once in a generation gathering of artists and fans" and "a true, must-see music event."
Other notable performers at the inaugural event include Alicia Keys, Rascal Flatts and the Black Eyed Peas, with more performers to be added to the roster throughout the summer.
