Lee Hyun-seo

Leeseo, born Lee Hyun-seo on February 21, 2007, in Seoul's Seocho-gu, came to public attention as a child when a 2009 moment with actress Han Hyo-joo on the SBS program One Night of TV Entertainment went viral. Before joining a girl group, she worked as a kids model at SM Entertainment. In 2021, Starship Entertainment introduced her as the final member of their new group, Ive, alongside Jang Won-young, and she debuted as a vocalist on December 1 with the single album Eleven. The song topped South Korean charts immediately, and the group later earned both the Rookie of the Year award and the Song of the Year Daesang (grand prize).

At 19, Leeseo has been active in the industry since 2018, an eight-year span that includes her pre-debut years as a model. She stands 5'5" with a slim build, brown hair, and brown eyes.

She is a South Korean singer and K-pop Idol. Her Instagram following has grown to 2.8 million, a figure that reflects the group's reach.

Even as one of the youngest members of Ive, Leeseo's early viral moment remains a notable footnote in her trajectory from child model to chart-topping idol. Her career continues to develop within Starship Entertainment, where she contributes as a vocalist.
