[Dispatch=Reporter Ku Min-ji] LE SSERAFIM is attending a major American music festival as the first K-pop girl group to do so.

U.S. radio platform iHeartRadio unveiled additional lineup for the '2026 iHeartRadio Music Festival' on the 1st. LE SSERAFIM has joined.

The 'iHeartRadio Music Festival' is a flagship American event held annually by iHeartRadio. This year it will be held on September 18 at the T-Mobile Arena in Las Vegas, USA.

LE SSERAFIM has been added to the lineup alongside global pop artists including BTS, Cardi B, and Snoop Dogg. LE SSERAFIM will be the first K-pop girl group to perform on this festival's stage.

The performance will be broadcast live through more than 150 'iHeartMedia radio stations.' It will also be live-streamed on OTT platforms Disney+ and Hulu. Plans are in place to share the experience with global listeners.

Ryan Seacrest will be hosting. LE SSERAFIM previously met him at the American New Year's Eve event 'Dick Clark's New Year's Rockin' Eve with Ryan Seacrest 2026,' which they attended as the first K-pop girl group.

They will close the global gaming festival 'BlizzCon 2026' on September 13. It marks their participation three years after being invited to 'BlizzCon' as the first K-pop artists in 2023. They will also hold a North American tour during this period.

Meanwhile, LE SSERAFIM will open the curtain on their second world tour 'PUREFLOW' at Incheon Inspire Arena on the 11th-12th. The second show is completely sold out, testament to their high interest.

They are currently beloved for 'Iconic by Mistake,' a collaboration with ILLIT and KATSEYE. The track ranked 43rd on Billboard's main song chart 'Hot 100' (as of July 4). It charted for two consecutive weeks.
