Sept. 22 may mark the first day of autumn, but in 2017, that is going to be one of the hottest days of the year -- at least for those who are lucky enough to make it out to Las Vegas. The iHeartRadio Music Festival kicks off Sept. 22, beginning two star-studded days that will include some of the biggest names in music, and this year's lineup has finally arrived.

The 2017 roster includes The Weeknd, Miley Cyrus, Harry Styles, Coldplay, DJ Khaled, Chris Stapleton, Lorde, Kings of Leon, Big Sean, P!NK, Thirty Seconds to Mars, Niall Horan, David Guetta, Thomas Rhett, and a special guest performance by Kesha, iHeartRadio announced Tuesday (July 18). As if that's not enough to make your head spin, the fest promises there's more to be revealed later this summer. 

Along with the headliners, the iHeartRadio Music Festival will also feature a performance from this year's Macy's iHeartRadio Rising Star winner, James Maslow, formerly of Nickelodeon-made boy band Big Time Rush. And before the nighttime craziness begins on Sept. 23, there's plenty of great music to be heard by festivalgoers in the Daytime Village Presented by Capital One® across from the Luxor Hotel and Casino. Migos, Halsey, Flume, Little Mix, French Montana, Niall Horan, Bleachers, Kelsea Ballerini, Judah & The Lion, Bebe Rexha, Noah Cyrus, Hey Violet, Cheat Codes, All Time Low, Khalid and Julia Michaels will all be performing at the Las Vegas Village.

The iHeartRadio Music Festival main stage performances will take place in Las Vegas' T-Mobile Arena and will be hosted by Ryan Seacrest. Both the night and daytime performances will be live streamed by The CW Network on CWTV.com and The CW App. The network will also air a broadcast special of the fest on Oct. 4 and 5 from 8 to 10 p.m. EST/PST.
