LE SSERAFIM to headline iHeartRadio Music Festival — first K-pop girl group on the lineup
LE SSERAFIM becomes the first K-pop girl group to perform at the 2026 iHeartRadio Music Festival, taking the stage Sept. 18 at T-Mobile Arena in Las Vegas.
LE SSERAFIM will perform at the 2026 iHeartRadio Music Festival on September 18 at T-Mobile Arena in Las Vegas. No K-pop girl group has played the festival before.
The Vegas date sits in the middle of September chaos. Their second world tour, Pure Flow, kicks off September 11 and 12 at Inspire Arena in Incheon. A North American leg starts September 16 in Los Angeles and stretches across 9 cities.
Five days before the iHeartRadio set, they'll close out BlizzCon 2026 on September 13. They were the first K-pop act invited to BlizzCon at all, back in 2023—this is a return trip. The closing-ceremony slot comes before the Las Vegas festival date, packing four major engagements into 18 days.
The iHeartRadio appearance continues a string of U.S. entertainment firsts since 2023.
