Who Is Jeongyeon?
Jeongyeon is a lead vocalist of TWICE, the JYP Entertainment girl group known for hits like “Cheer Up” and “Feel Special.” Born Yoo Jeong-yeon on November 1, 1996, in Suwon, South Korea, she’s affectionately nicknamed the “mom of TWICE” for her steady, caring energy within the group.
Early Life and Trainee Years
Jeongyeon was originally named Yoo Kyung-wan at birth but legally changed her name in the third grade after classmates teased her for having a name that sounded masculine. After initially failing a JYP audition, she passed the company’s 6th Open Audition in March 2010 and began training, later choosing JYP over a same-day acceptance from SM Entertainment.
Debut and Life with TWICE
She finished second on the 2015 survival show SIXTEEN and debuted with TWICE that October in The Story Begins. Since then, her rich, husky vocal tone has anchored the group’s biggest hits, from Twicetagram and Feel Special to 2025’s This Is For. Jeongyeon took two separate hiatuses, in 2020 and 2021, to focus on her health, returning each time to strong support from ONCE.
Solo Work and New Ventures
In 2025, Jeongyeon stepped into new creative territory with “Fix a Drink,” her first individual solo track, included on TWICE’s studio album This Is For. That same year, she was announced to make her acting debut in the film Recruits: The Movie, becoming the second TWICE member to branch into acting.
Personality and Personal Life
Known for her dry sense of humor and “girl crush” stage charisma, Jeongyeon can play both saxophone and guitar, enjoys building Legos and Nanoblocks, and is famously the member in charge of keeping the TWICE dorm tidy.
