The iHeartRadio Music Festival in Las Vegas is heading into its third year, and the fest has rightly earned its reputation for having the biggest pop talent, like, ever: The just-announced line-up features an absurd roster of performers, including Justin Timberlake and Katy Perry on the main stage with Miley Cyrus and Avril Lavigne in the adjacent iHeartRadio Music Festival Village, which will feature multiple smaller stages.
There’s a few other names with which you’re likely familiar, too: fun.! Bruno Mars! Adam Lambert! Maroon 5! Miguel! Ke$ha! Jason Derulo! Elton John! And a lot of others, too.
The festival will be held September 20-21 at Vegas’ MGM Grand Arena, with a full list of performers to be formalized closer to the date. See all the announced performers below.
