LE SSERAFIM Makes iHeartRadio Music Festival History as First K-POP Girl Group

LE SSERAFIM has become the first K-POP girl group to perform at the iHeartRadio Music Festival.

Chaewon, Sakura, Yunjin, Kazuha and Hong Eunchae took the stage at the 2026 iHeartRadio Music Festival at T-Mobile Arena in Las Vegas on September 19, delivering a roughly 30-minute set.

Ahead of the performance, the members reflected on the milestone during an interview, saying, "We heard that we are the first K-POP girl group to participate, so we feel even more honored and excited. We prepared some great songs, and we hope everyone enjoys them."

Introduced as "K-POP superstars," LE SSERAFIM took the stage following Benson Boone and opened with their latest single "Made My Night."

After the first song, the group told the audience, "Just like ‘Made My Night,' we're going to make your night special," before continuing with "BOOMPALA" and "Saki (feat. Aliyah's Interlude)."

The set also included "ICONIC BY MISTAKE," which previously spent eight consecutive weeks on the Billboard Hot 100, before LE SSERAFIM closed out the latter portion of their performance with "SPAGHETTI (feat. j-hope of BTS)" and "CRAZY."

iHeartRadio highlighted the group throughout the event, sharing photos from the blue carpet and writing on social media that the five members had made a "dazzling entrance as always." During their set, the festival also praised the group for bringing "incredible energy" to the stage.

LE SSERAFIM also crossed paths with several of the weekend's other performers. The members were spotted watching Zara Larsson's performance on September 18, while Larsson later shared a photo with the group on social media.

The group also shared a photo with BTS, who performed at the festival on September 19. This year's lineup additionally included Cardi B, Snoop Dogg and other artists.

The festival appearance comes during a busy stretch of U.S. activities for LE SSERAFIM. The group debuted "Made My Night" live at BlizzCon 2026 on September 13 before opening the U.S. leg of its PUREFLOW tour in Los Angeles on September 16.

LE SSERAFIM will continue the tour with its second U.S. concert at the Tacoma Dome on September 20.
