Lia ITZY - Biography, Profile, Facts, and Career

Choi Jisu, or popularly known as Lia, is a South Korean singer. She is a member of the girl group ITZY.

Lia became famous after debuting as a sub-rapper and vocalist in ITZY.


She began to start her footsteps as a Kpop idol when she joined an audition for SM Entertainment.

When she was just an elementary student in Canada, Lia attended SM’s audition. Because her talent and her visual is amazing, she passed the audition.

Unfortunately, she couldn’t sign the contract with SM Entertainment. It’s because she doesn’t get her parent’s permission for being a trainee.

Later, she finally became a JYP Entertainment trainee when she was just in the 9th grade. She really worked very hard to become a Kpop idol during her trainee days.

Her hard work finally shows its result. Lia eventually was being revealed as a member of ITZY on January 20, 2019 through Prologue Film.
