HYBE girl groups Le Sserafim, Illit, and Katseye announced they will release a collaborative single titled "Iconic By Mistake" on June 12, 2026, at 1 p.m. KST (noon Malaysian time) [1, 2, 3, 4]. This marks the first official track featuring all three groups together [1, 2, 3, 4].

Le Sserafim debuted in 2022 as a five-member girl group known for performance-focused hits like their recent single "Boompala" [1, 2, 3]. Illit made their debut in 2024 through the survival program R U Next?, gaining international recognition with songs such as "Magnetic" and "It's Me" [1, 2, 3]. Katseye, formed through the HYBE-Geffen global girl-group project, won three trophies at the 2026 American Music Awards, including New Artist of the Year [1, 2, 3].

HYBE labels described the three groups as "known for distinct musical styles and growing global followings" [1]. Despite their different sounds, the groups share frequent private interactions and a strong desire to perform together [3, 4]. Katseye's success at the American Music Awards in May 2026 highlighted their rising global profile [1, 2].

NewJeans, another popular HYBE girl group, is not participating in the collaboration. Sources say this is due to ongoing disputes with HYBE management, though this is not confirmed in all reports [3, 4].

Ahead of the single's release, Le Sserafim, Illit, and Katseye will premiere "Iconic By Mistake" live on the music show "M Countdown" on June 11, 2026 [3]. The official release will follow the next day simultaneously across platforms.

The single is set to drop on Friday, June 12 at 1 p.m. KST (12 p.m. Malaysian time), marking a major event for HYBE's girl group roster [1, 2, 3, 4].
