Yet another major music name has been added to the star-studded iHeartRadio Music Festival. Childish Gambino will take the stage on September 21 during the two-day concert in Las Vegas.

The rapper's recent single, "This is America," skyrocketed into viral territory with its socially conscious music video, vaulting all the way to No. 1 on the Billboard Hot 100.

The two-day event, hosted by Ryan Seacrest, also includes previously announced performers Justin Timberlake, Fleetwood Mac, Carrie Underwood, Mariah Carey, Imagine Dragons, Jason Aldean, Sam Smith, Luke Bryan, Lynyrd Skynyrd, Panic! at the Disco, Kelly Clarkson, Shawn Mendes, Kygo, Rae Sremmurd and Logic.

The iHeartRadio Music Festival will take place September 21 and 22. at the T-Mobile Arena in Las Vegas and will broadcast live on iHeartMedia radio stations across the United States. The CW Network will also exclusively live-stream both nights of the festival via CWTV.com and The CW App.
