LE SSERAFIM made history at the 2026 iHeartRadio Music Festival by becoming the first KPop girl group to perform at the major U.S. event. Members Chaewon, Sakura, Yunjin, Kazuha, and Eunchae took the stage at T-Mobile Arena in Las Vegas on September 19, 2026, following Benson Boone’s performance. The “Crazy” performers also joined the lineup with A-list artists that included BTS, Cardi B, and Snoop Dogg.

During a pre-performance interview, the group said they were honored to make history at the festival and hoped the audience would enjoy the songs they had prepared for them. LE SSERAFIM then delivered an approximately 30-minute set, opening with their new single “Made My Night,” made in collaboration with Overwatch.
“We heard this is the first time a K-pop girl group has participated, so we feel honored and excited. We’ve prepared good songs, so we hope everyone enjoys them,” LE SSERAFIM shared.
After the performance, the members told the audience that they wanted to make their night special, hinting at the message of their latest single. The group had already spent time at the festival venue the previous day, watching dance-pop artist Zara Larsson perform. LE SSERAFIM also met with their label mates, BTS, who performed on September 18. The two KPop stars took photos of the moment, drawing attention from fans. The festival appearance adds another United States achievement for the group as they continue promoting their music for American audiences.
