LE SSERAFIM iHeartRadio 2026 locked in as the clear night-two search phrase after the five-member Hybe act took T-Mobile Arena in Las Vegas on Saturday, 19 September 2026—the first time a K-pop girl group has performed at the iHeartRadio Music Festival. The Korea Herald’s same-weekend report and iHeartMedia’s earlier lineup note both treat that milestone as the headline, not a footnote beside BTS’s Friday close.

For readers typing “LE SSERAFIM setlist,” “Made My Night live,” or “first girl group iHeartRadio,” this BREAKING desk piece maps the verified song order, stage look, backstage Hybe crossover and how the set deepens our Music live / K-pop cluster without twinning Friday’s BTS write-up.

The setlist: Made My Night to Crazy

The Korea Herald lists a six-song arc for the Las Vegas main stage:

• Made My Night — latest release, built with Blizzard Entertainment’s Overwatch game partnership; Yunjin framed the opener as a Vegas-night invitation.

• Boompala — lead track from the recent LP ‘Pureflow’, Pt. 1.

• Iconic By Mistake — June collaboration with Illit and Katseye; LE SSERAFIM performed a shortened cut featuring only its own section.

• Saki

• Spaghetti — the track that previously featured J-Hope, tying the set to the broader Hybe live weekend.

• Crazy

That spine answers the practical Trends query: yes, the night mixed the new Pureflow-era material with catalogue hammers and the Overwatch collab as a festival cold open—not a nostalgia-only medley.

First K-pop girl group on the iHeartRadio main stage

Huh Yunjin said in a pre-show interview quoted by The Korea Herald: “It’s our first time performing here, so it’s an absolute honor… We also heard that it’s the first time a K-pop girl group has participated in the show, so we’re really honored and excited.” iHeartMedia’s lineup announcement had already named LE SSERAFIM alongside BTS, Cardi B, Muse, Snoop Dogg, Zara Larsson and others for the Capital One–presented two-night event.

Visually, the group leaned into Western-inspired staging—cowboy boots, plaid and denim—that matched the Las Vegas room rather than a Seoul showcase transplant. After Made My Night and Boompala, Yunjin told the crowd that Vegas “doesn’t do anything halfway,” pairing the city’s reputation with the group’s own performance pitch.

How this sits beside BTS night one

Friday’s BTS close and Saturday’s LE SSERAFIM set were deliberately consecutive Hybe bookings. Source Music posted a backstage photo of both acts; The Korea Herald notes prior musical crossovers (Yunjin on a 2024 J-Hope solo cut; J-Hope later on Spaghetti). Treat those as verified context, not a joint encore claim—each night kept its own set identity.

LE SSERAFIM’s 2026 festival run already included Summer Sonic in Japan and a BlizzCon main-stage close in Anaheim on 13 September, so iHeartRadio reads as a U.S. radio-festival peak rather than a one-off debut.

People also ask: was Monsta X the earlier K-pop exception?

Older festival desks sometimes cite Monsta X’s 2019 Daytime Stage appearance. The Korea Herald and Korea Portal framing for 2026 still treat LE SSERAFIM as the first girl group on this festival’s main narrative stage—keep that distinction if you are writing social captions.

Why this Music live / K-pop cluster piece now

Clip shares spike setlist and “first girl group” queries within hours of a Las Vegas close. Pair this piece with our live BTS iHeartRadio 2026 (https://www.thesundayprofile.com/bts-iheartradio-2026) night-one setlist hub and the earlier Dubai K-Fest 2026 (https://www.thesundayprofile.com/dubai-k-fest-2026-free-kpop) free K-pop culture note—same cluster, different geo and billing.
