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.
