LE SSERAFIM Makes History as First K-pop Girl Group to Perform at iHeartRadio Festival, Shares Special Moment with BTS

LE SSERAFIM became the first K-pop girl group to perform at the U.S.’s premier music festival, the iHeartRadio Music Festival, winning an enthusiastic response from local audiences. Photos of the group with BTS also surfaced, drawing attention to the special meeting between two leading names in K-pop on the global stage.

LE SSERAFIM attended the 2026 iHeartRadio Music Festival at T-Mobile Arena in Las Vegas on the 19th (local time). Following BTS’s performance the previous day, LE SSERAFIM took the stage on the second day, with both acts appearing at the festival on consecutive days. Ahead of their performance, LE SSERAFIM shared photos with BTS on the group’s official social media on the 18th, capturing the attention of fans worldwide.

The two groups’ connection has also extended to musical collaborations. In 2024, Huh Yunjin contributed to a track on j-hope’s solo album, while j-hope featured on LE SSERAFIM’s “SPAGHETTI.” This meeting held added significance as another chapter in their musical exchange.

That day, LE SSERAFIM took the stage after Benson Boone’s performance, introduced as “K-pop superstars.” During their roughly 30-minute set, they opened with their new song “Made My Night,” followed by their second studio album’s title track and b-sides including “BOOMPALA” and “Saki (feat. Aliyah’s Interlude).” After the opening song, the members said, “Just like ‘Made My Night,’ we’ll make your night special,” expressing their determination for the performance.

When “ICONIC BY MISTAKE” began, the audience erupted in even louder cheers. The song was introduced as a special collaboration single that spent eight consecutive weeks on Billboard’s main songs chart, the Hot 100. Later in the set, “SPAGHETTI (feat. j-hope of BTS)” and “CRAZY” followed, with the crowd enjoying the performance and jumping along to the members’ cues.

iHeartRadio shared blue-carpet photos of LE SSERAFIM on its official social media, saying that they “arrived looking dazzling, as always.” During the performance, the group was praised for “lighting up the stage with incredible energy.” In a pre-show interview, LE SSERAFIM said they felt especially honored and excited to be the first K-pop girl group to participate, and hoped everyone would enjoy all the songs they had prepared.

Recently, LE SSERAFIM also performed at Japan’s Summer Sonic 2026 and the U.S.’s BlizzCon 2026, and made their third appearance on the U.S. talk show The Jennifer Hudson Show. On the 16th, they completed the first U.S. tour stop in Los Angeles, with their second performance scheduled for the 20th at the Tacoma Dome. Attention is growing around LE SSERAFIM’s next steps as they continue expanding their presence on the global stage.
