Early lifeEdit

Jeongyeon was born on 1 November 1996 as Yoo Kyung-wan in Suwon, Gyeonggi, South Korea.[1] She is the younger sister of the actress Gong Seung-yeon.[2]



She joined JYP Entertainment after passing the sixth open audition on 1 March 2010.[citation needed] From 2013 to early 2015, it was expected that Jeongyeon would become a member of the new JYP girl group, 6mix, along with current Twice members Nayeon and Jihyo. However, this new project was cancelled and in the end they did not debut.[3][4]

2015–present: Sixteen, Twice and solo activitiesEdit

In 2015, Jeongyeon competed in the survival program Sixteen, which was to determine the final members of the girl group Twice. In the final episode, she was chosen to be one of the members.[5]

She and her sister co-hosted the South Korean music program Inkigayo from July 2016 to January 2017,[2][6] for which they both won the Newcomer Award at the 2016 SBS Entertainment Awards.[7]

In Gallup Korea's annual music poll, Jeongyeon was voted among the top 20 most popular idols in South Korea for three consecutive years from 2016 to 2018, alongside her bandmates Nayeon and Tzuyu.[8][9][10][11]
