ILLIT is broadening their sound by collaborating with top U.S. producers.

On November 3, the group unveiled the track motion video for their first single album NOT CUTE ANYMORE through HYBE Labels' official YouTube channel.

The release includes two tracks, led by the title song NOT CUTE ANYMORE, which boldly expresses the desire to break free from a purely "cute" image. The track is produced by Jasper Harris, known for Jack Harlow's Billboard Hot 100 No. 1 hit "First Class" and Lil Nas X's Grammy-nominated "Montero."

Global songwriters such as Sasha Alex Sloan and youra also contributed, adding depth to the project. The collaboration between ILLIT and world-class producers is expected to bring a refreshing synergy.

The B-side track NOT ME carries a message of self-definition and empowerment, declaring that no one can define who they are. U.S. producer duo Pebbles and TamTam took part in its production, with ILLIT members YoonA, Minju, and Moka joining the songwriting credits.

Through this single, ILLIT explores the contrast between how the world perceives them and how they see themselves, revealing their honest perspectives. Concept photos for the new release will drop on November 10 and 12.

Ahead of their comeback, ILLIT will hold 2025 ILLIT GLITTER DAY IN SEOUL ENCORE concerts at Olympic Hall in Seoul on November 8 and 9.
