LE SSERAFIM Joins BTS, Cardi B at 2026 iHeartRadio Music Festival

LE SSERAFIM will become the first K-POP girl group to perform at the iHeartRadio Music Festival, adding another major U.S. event to its 2026 schedule.

The group was announced Tuesday as part of the lineup for the 2026 iHeartRadio Music Festival, which will be held Sept. 18 at T-Mobile Arena in Las Vegas. LE SSERAFIM will perform alongside artists including BTS, Cardi B and Snoop Dogg. The event will be broadcast across more than 150 iHeartMedia radio stations and livestreamed on Disney+ and Hulu.

The appearance marks another collaboration with host Ryan Seacrest, following LE SSERAFIM's performance at "Dick Clark's New Year's Rockin' Eve" earlier this year.

The festival is part of a busy North American schedule for the group. LE SSERAFIM will first headline the closing ceremony of BlizzCon 2026 on Sept. 13 before launching the North American leg of its "PUREFLOW" world tour in Los Angeles on Sept. 16, with concerts planned in nine cities.

The group will kick off the tour with two sold-out shows at Inspire Arena in Incheon on July 11 and 12. LE SSERAFIM is also continuing promotions for the collaboration single "ICONIC BY MISTAKE," which recently spent a second consecutive week on the Billboard Hot 100.
