iHeartRadio Festival Adds First K-Pop Girl Group

LE SSERAFIM becomes first K-pop girl group to perform at iHeartRadio’s Vegas festival, Sept. 18-19

Published July 17, 2026

LE SSERAFIM just made festival history. The K-pop group joined the lineup for the 2026 iHeartRadio Music Festival presented by Capital One, becoming the first K-pop girl group to perform at the two-day event at T-Mobile Arena. The festival returns Friday, Sept. 18 and Saturday, Sept. 19, with a bill that also includes BTS, Cardi B, Kenny Chesney, Muse and Snoop Dogg. For anyone planning a September trip, the addition means another packed weekend on the Strip, and another reason to lock in your other Vegas plans early.

A Lineup Built for a Big Weekend

iHeartMedia confirmed the full bill in a press release, and it is stacked. Alongside LE SSERAFIM, BTS, Cardi B, Kenny Chesney and Snoop Dogg, the two nights also feature Muse, Benson Boone, Goo Goo Dolls, Lainey Wilson and Major Lazer. The festival has become one of the biggest recurring music events on the Vegas calendar, drawing a mix of pop, hip-hop, country and rock fans into T-Mobile Arena for a single weekend. If you would rather catch a show without festival crowds, plenty of Las Vegas music shows run all September long on smaller stages across the Strip.

Why LE SSERAFIM’s Booking Matters

K-pop’s footprint in Las Vegas keeps growing, and this booking is a marker of it. LE SSERAFIM is the first K-pop girl group to perform at the iHeartRadio Music Festival, a lineup that has historically leaned toward US pop, country and hip-hop acts. It signals festival organizers are chasing the same global fanbases that have packed arenas from Seoul to Los Angeles, and it gives K-pop fans flying into Vegas a reason to build a longer trip around the weekend. Between festival sets, visitors who want a polished, high-production night out have plenty of Las Vegas production shows to fill the rest of the itinerary.

What This Means for Your Vegas Trip

Because the festival lands on a weekend, expect the Strip, and especially hotels near T-Mobile Arena like MGM Grand, Park MGM and New York-New York, to book up fast for Sept. 18-19. If you are building a trip around the festival, pair it with a show earlier in the week. Scorpions play select nights at Planet Hollywood between Sept. 17 and Oct. 3 with tickets from $72, and Zoe plays Caesars Palace on Sept. 12 from $123. Both give festival-goers a second live show without competing for the same arena tickets. Check what else is running that week with shows in Las Vegas this weekend before you lock in hotel dates.

The iHeartRadio Music Festival is going to be one of the busiest weekends of the Vegas fall calendar. Whether you are flying in for LE SSERAFIM, BTS or Cardi B, book your other Strip entertainment through Spotlight now, before the best seats for the week are gone.
