LE SSERAFIM is heading to the iHeartRadio Music Festival this fall. The group was announced as a new addition to the 2026 festival lineup on June 30, joining BTS as part of the star-studded performer roster.

The two-day festival runs September 18–19 at T-Mobile Arena in Las Vegas, with BTS set as one of the headliners. iHeartMedia's announcement of LE SSERAFIM's participation marks another major international stage for the group, continuing their momentum on the global music circuit.

This comes on the heels of BTS's continued chart dominance. Their album ARIRANG recently made history as the first Korean artist release to spend 12 weeks in the top 10 of the Billboard 200—a milestone that underscores K-pop's expanding footprint in mainstream Western markets. LE SSERAFIM's inclusion on the iHeartRadio lineup further reflects how Korean artists are becoming central fixtures at major U.S. music events.

LE SSERAFIM, the five-member HYBE group formed in 2022, has steadily built their presence internationally since debut. The group includes members Huh Yunjin and Kazuha, who bring cross-cultural appeal to their performances. Their addition to the festival signals iHeartRadio's commitment to featuring diverse global artists alongside established acts.

The iHeartRadio Music Festival is one of the largest annual music events in the U.S., typically attracting tens of thousands of fans and featuring performances across multiple genres. Past festivals have included major pop, hip-hop, and rock acts, making the inclusion of both BTS and LE SSERAFIM notable for K-pop's continued integration into American mainstream music culture.

More artists are expected to be announced as the September event approaches. Fans interested in attending can keep tabs on iHeartRadio's official channels for ticket information and the full lineup reveal.
