Lia (리아) is a South Korean singer and member of ITZY. Discover her age, height, MBTI, birthday, solo OSTs, hiatus story, fun facts, career journey, and why fans admire ITZY's main vocalist.
Lia was born as Choi Ji Su in Incheon, South Korea. During childhood, she spent part of her early years living in Toronto, Canada, where she became fluent in English. Her English name, Julia, was given to her by her aunt, and it later inspired her stage name, "Lia." While living in Canada, she successfully auditioned for SM Entertainment, but her parents chose not to let her pursue training at the time. Years later, she auditioned for JYP Entertainment and entered the company's Female Vocal Club, where her exceptional singing ability quickly stood out.
Despite training for just over two years—the shortest training period among ITZY's members—Lia debuted as the group's main vocalist on February 12, 2019. She has since become known for her warm vocal tone, emotional OST performances, and calm personality. Outside of ITZY, Lia has built a successful reputation as an OST singer through songs for popular Korean dramas and officially returned to group activities in 2024 after taking time away to prioritize her mental health, earning admiration for her honesty and resilience.
