LE SSERAFIM become first K-pop girl group to perform at iHeartRadio Music Festival
LE SSERAFIM took the T-Mobile Arena stage in Las Vegas on Sept. 19, opening their 30-minute set with new single 'Made My Night'.
First K-pop girl group on the iHeartRadio stage
LE SSERAFIM performed at the 2026 iHeartRadio Music Festival on September 19 at T-Mobile Arena in Las Vegas. They became the first K-pop girl group to appear at the festival. The set ran approximately 30 minutes.
Made My Night opened the show. What followed was a six-song stretch: BOOMPALA (a title track and B-side from their second regular album), Saki (feat. Aliyah's Interlude), ICONIC BY MISTAKE, SPAGHETTI (feat. j-hope of BTS), and CRAZY. ICONIC BY MISTAKE had already spent eight consecutive weeks on the Billboard Hot 100 heading into the show.
Before performing, the five members reflected on the moment: "We heard this is the first time a K-pop girl group is participating, so it feels even more honorable and exciting."
A week of US activity
The Las Vegas date landed in the middle of a packed American run. LE SSERAFIM first performed Made My Night publicly at BlizzCon 2026 on September 13. Three days later, they opened their 2026 LE SSERAFIM TOUR 'PUREFLOW' IN UNITED STATES in Los Angeles on September 16. Tacoma Dome was next, scheduled for September 20.
On September 18, the day before iHeartRadio, the group attended the festival and watched Zara Larsson perform. Larsson posted a photo with LE SSERAFIM on social media afterward. They also shared a photo with BTS, who performed at the same festival.
Fans who missed the Las Vegas broadcast got another chance. A pre-recorded Made My Night stage was set to air on SBS Inkigayo on September 21 at 12:05 AM.
