Early Life and Background
Leeseo was born Lee Hyun-seo on February 21, 2007, in South Korea. Before joining Starship Entertainment, she worked as a child model under SM Entertainment, giving her early, formative experience in front of a camera well before she ever became a K-pop trainee at a different agency.
On November 8, 2022, Starship Entertainment announced that Leeseo had been accepted into Hanlim Multi Art School’s Broadcasting and Entertainment department, allowing her to continue her formal education alongside her growing idol career.
Career Highlights
Debut and IVE’s Formation Leeseo officially debuted as IVE’s youngest member on December 1, 2021, with the single album Eleven, making her the group’s maknae at just 14 years old. The title track’s music video drew 45 million views within days of release, and IVE earned their first music show win just seven days after debut.
Early Brand Collaborations Even before IVE’s official debut concept had fully taken shape, Leeseo was already gaining individual visibility.
On June 6, 2022, it was announced that she, alongside fellow member Wonyoung, would participate in a collaborative digital single titled “Blue & Black,” released June 28, 2022, as part of an ongoing partnership between Starship Entertainment, Pepsi, and several other Starship-affiliated groups including Oh My Girl and Cravity.
In December 2022, she starred in a beauty pictorial for Dazed Korea, further building her individual fashion and media presence early in her career.
A String of Genre-Defining Hits As IVE’s visual and youngest member, Leeseo contributed to the group’s rapid string of hits, including “Love Dive” (April 2022), which won Song of the Year at both the 2022 MAMA Awards and Melon Music Awards, and “After Like” (August 2022), which sold 1.7 million albums overall.
She continued performing across the group’s subsequent releases, including I’ve Mine (2023), Ive Switch (2024), Alive (2024), Be Alright (2025), and Ive Secret (2025).
Continued Fashion Presence In October 2025, Leeseo and fellow member Gaeul appeared together on Allure Korea’s digital cover in collaboration with Crocs, continuing the individual fashion visibility she’d begun building years earlier with her Dazed Korea pictorial.
Global Milestones IVE performed at Lollapalooza in 2024 and embarked on their first world tour that same year. As of their most recent tally, IVE has earned 99 wins against 208 award nominations. In late February 2026, the group returned with a highly anticipated full-length album comeback that Korean media described as “the return of K-pop queens.”
Personality and Public Image
As IVE’s youngest member, Leeseo has been affectionately teased by fellow members for her playful, sometimes cheeky personality, with fellow members joking about her tendency to jump into conversations at unexpected moments during group interviews.
Her early modeling background as a child gave her a natural comfort in front of cameras that’s carried directly into her role as one of IVE’s core visuals. Despite joining the group at just 14 years old, she’s grown alongside IVE’s rapid rise, developing into one of the group’s more visually recognized individual faces in Korean fashion media.
That growth has been especially visible to longtime fans who first watched Leeseo navigate IVE’s earliest, most demanding promotional schedules as the group’s youngest and least experienced member, only to see her mature into a confident, camera-ready presence in her own right.
Her continued academic pursuits at Hanlim Multi Art School, balanced alongside an increasingly busy promotional and fashion schedule, reflect a level of discipline uncommon for someone who debuted so young.
Fans following her individual fashion features have noted a visible evolution in her personal style and on-camera confidence between her earliest pictorials and her more recent Allure Korea cover.
