The 2016 iHeartRadio music festival announced its blockbuster line-up on Monday, and it is a hell of a spread. The annual festival features some of the music industry's biggest acts this year, including Drake, Britney Spears, Ariana Grande, Usher, Sia, Pitbull and U2. The two-day event will be held in Las Vegas on Sept. 23-24, and will be live streaming on CWTV.com, according to a statement from the festival's organizers.

"This year's show is a complete cross section of the best artists from every genre of music. The weekend will be a true representation of the diveristy of our iHeartRadio stations across the country as well as the music you find on the iHeartRadio app."
