There's no need to go all the way to Las Vegas to see Mariah Carey, Fleetwood Mac, Childish Gambino and more of music's biggest stars in concert this weekend: Stay in your sweats, order some takeout, and watch day 1 of the 2018 iHeartRadio Music Festival from the comfort of your own home -- or from your friend's house party, or from the club, or really wherever you'll be on Friday night (Sept. 21).

The annual A-list musical gathering kicks off Friday at 10 p.m. ET/7 p.m. PT from Vegas' T-Mobile Arena with a stacked lineup that also includes Jack White, Jason Aldean, Sam Smith, Panic! at the Disco, Kygo, Rae Sremmurd and Macy's Rising Star winners Heffron Drive.

You can tune in to the live stream starting at 10 p.m. ET via CWTV.com or The CW app. In addition to all the night's performances, morning radio host Elvis Duran will be backstage for exclusive artist interviews that will air on iHeartMedia radio stations across the country and on the iHeartRadio app.

Then, on Oct. 7-8, The CW will broadcast a two-night special on the festival, airing 8-10 p.m. ET.
