Leeseo
Leeseo (이서), born Lee Hyun-seo (이현서) on February 21, 2007, debuted with IVE at 14 and immediately proved that age is irrelevant when stage presence is that commanding. The youngest member of Starship Entertainment's six-member group, Leeseo trained as a child model for SM Entertainment Kids before switching agencies and joining the IVE lineup for their December 2021 debut.
Her role in IVE spans lead dancer, sub-vocalist, and visual -- a trio of positions she carries with a naturally expressive charisma. In February 2024, she released "May Lily," an original soundtrack for the Naver Webtoon series I'm the Queen in This Life, marking her first solo vocal release outside the group. In April 2024, she became an MC on SBS's flagship music show Inkigayo, a role she held for one year and seven months before stepping down in December 2025. Outside IVE's group schedule, she has served as brand ambassador for The North Face (2023) and THE SAEM (2025).
In 2025, IVE released IVE EMPATHY, and in February 2026 the group dropped their second studio album REVIVE+ with pre-release single "Bang Bang," which achieved a perfect all-kill. Leeseo's solo contribution to the era came via the track "Super ICY." She handles the youngest-member energy with uncommon confidence -- a performer who debuted young and has been closing the age gap with her resume ever since.
