Felix Lee

Felix Lee was born and raised in Sydney, Australia, to Korean parents. Growing up in Sydney alongside his older sister Rachel and younger sister Olivia, he attended St Patrick's Marist College. During his childhood, he was an active athlete, practicing swimming and competing in taekwondo, in which he attained a second-degree black belt and won several competition awards.

In 2016, Felix received an invitation to audition for JYP Entertainment. He chose to finish his schooling in Australia before moving to South Korea in February 2017 to join the agency as an apprentice. Over a training period of roughly ten months, he studied Korean and trained alongside his future bandmates.

In October 2017, Felix took part in the Mnet reality survival show Stray Kids, designed to determine the final lineup of the new boy band. During the eighth episode of the competition, he was eliminated from the lineup. However, he and fellow trainee Lee Know were brought back for the ninth episode, earning their spots in the final group through public support and successful completion of the final mission.

Felix officially debuted with Stray Kids on March 25, 2018, with the release of the EP I Am Not, featuring the single "District 9". He took an active role in the group's creative output from the beginning, co-writing the track "Mixtape #1" for their debut release.

Following Stray Kids' debut, Felix continued to contribute as a rapper, dancer, and lyricist across their releases. He co-wrote several tracks for the group's subsequent projects, including "WHO?", "Mixtape #2", "Mixtape #3", and "Mixtape #4" across the I Am Who, I Am You, and Clé 1: Miroh mini-albums. In 2020, he collaborated with bandmates Lee Know and Hyunjin as a co-writer on the unit track "WOW" for the repackaged album In Life.

From July 2019 to January 2020, Felix worked as the solo host for Arirang K-pop's television program Pops in Seoul, where he led a regular instructional segment titled "Felix's Dance How To!". In March 2021, he released the collaborative track "Cause I Like You" with bandmate Changbin for the SKZ-RECORD project, followed in June 2021 by the SKZ-PLAYER release "Up All Night" alongside Bang Chan, Changbin, and Seungmin. In February 2022, JYP Entertainment announced that Felix would temporarily limit his stage participation during performances to recover from a herniated disc.
