Story

Biography

Who Is Yubin?

Yubin, born Kim Yu-bin (김유빈) on October 4, 1988, in Gwangju, South Korea, is a South Korean rapper, singer-songwriter, and actress best known as the main rapper of the iconic girl group Wonder Girls. If you grew up on second-generation K-pop, chances are you remember her sharp raps and confident stage presence on hits like “Nobody” and “So Hot.”

Early Life and Trainee Days

Before she ever stepped on a JYP stage, Yubin’s family moved between Korea and San Jose, California, where she attended Leland High School. She later returned to Korea and eventually graduated from Myongji University with a degree in Film and Music. Interestingly, she almost debuted with a completely different group: in 2007, she was set to join a girl group called Five Girls alongside future stars G.NA, Hyoseong, UEE, and Jiwon, but the project fell apart before it ever launched.

Joining Wonder Girls

That setback turned into an opportunity. In September 2007, Yubin joined Wonder Girls as the group’s new main rapper, stepping in for original member Hyuna. From there, she became a key part of the group’s biggest era, contributing not just her rap verses but also her own written lyrics to songs like “Girls Girls” and “Sweet Dreams.” She even picked up the drums for the band’s “Wonder Girls: Reboot” concept.

Acting, Reality TV, and Life After Wonder Girls

Yubin didn’t stop at music. In 2013, she made her acting debut in the OCN drama The Virus, and in 2015 she turned heads as a contestant on Unpretty Rapstar‘s second season. When Wonder Girls disbanded in 2017, Yubin chose to stay with JYP Entertainment and pursue a solo career, debuting with the single “Lady” in 2018. She later struck out on her own entirely, founding her own label, RRR Entertainment, in 2020.

Why Fans Love Her

Whether it’s her love for scuba diving, her willingness to poke fun at herself on variety shows, or her steady presence across two decades in the industry, Yubin has built a reputation as one of K-pop’s most enduring and versatile artists. She continues to explore music, acting, and entrepreneurship well beyond her Wonder Girls days.
