LE SSERAFIM caught fans’ attention after sharing a rare group photo with BTS during the iHeartRadio Music Festival in Las Vegas.

On September 18, LE SSERAFIM posted the photo through the group’s official social media account ahead of their festival performance. The image showed the two HYBE groups together, bringing artists from different generations of the company into one frame.

BTS performed during the first day of the festival, while LE SSERAFIM was scheduled to take the stage on the second day.

The meeting also drew interest because members of the two groups have previously connected through music. In 2024, LE SSERAFIM’s Huh Yunjin participated in a track from j-hope’s solo album, while j-hope later featured on LE SSERAFIM’s song SPAGHETTI.

LE SSERAFIM’s appearance at the iHeartRadio Music Festival also marks another milestone in the group’s international activities, as they were invited as the first K-pop girl group to perform at the event.

The festival lineup also includes major international artists such as Snoop Dogg, Cardi B, and Benson Boone.

Following appearances at SUMMER SONIC 2026 in Japan and BlizzCon 2026 in the United States, LE SSERAFIM continues to expand its presence at major global events.

Still, it was the unexpected photo with BTS that became one of the most talked-about moments ahead of LE SSERAFIM’s performance, giving fans a rare look at the two groups together on the same international stage.
