LE SSERAFIM added to 2026 iHeartRadio Music Festival lineup alongside BTS

LE SSERAFIM have been confirmed for the 2026 iHeartRadio Music Festival, expanding this year’s line-up with another major K-pop name.

The group is scheduled to perform on September 19, the second day of the two-day event held at the T-Mobile Arena in Las Vegas.

BTS had already been announced as headliners and will take the stage on September 18, making this a notable festival weekend for K-pop fans.

The iHeartRadio Music Festival is known for mixing global pop acts with US chart-toppers, and this year’s bill also includes artists such as Cardi B, Muse, Snoop Dogg, Zara Larsson, and more.

For European fans planning a trip, the festival offers a rare chance to see both LE SSERAFIM and BTS on the same weekend in a large-scale US event setting.

The addition of LE SSERAFIM highlights their growing international presence, as they continue to secure high-profile festival slots outside Korea.
