NS Yoon-G (English name: Christine Kim; Korean name: Kim Yoonji; Hangul: 김윤지; born September 6, 1988), sometimes stylized as NS Yoonji, is a K-pop singer who debuted in 2009 with the digital single "Head Hurts" under JTM Entertainment. The NS in her name stands for "New Spirit". Yoon-G uses her Korean name as her stage name as she found "Christine" was difficult for Korean people to pronounce.
Yoon-G moved to San Fernando Valley, California in 4th grade, and studied at UCLA, graduating with a Bachelor's in Communication. Yoon-G is cousins with ex-Kara member, Kang Jiyoung, and has a younger brother. She moved back to South Korea to pursue her dream of becoming a singer, joining DSP Media as a trainee, before debuting with JTM Entertainment with single "Head Hurts".
On November 1, 2012, Yoon-G released a digital single, "If You Love Me", featuring Jay Park, and released an official music video as well as a behind-the-scenes version, showing Yoon-G and Jay Park in the studio together. Yoon-G performed her single on Korean music shows such as KBS' Music Bank, Mnet's M! Countdown, MBC's Music Core and SBS' Inkigayo, alongside Jay Park, who is occasionally replaced by Dalmatian's Simon.
Also in November 2012, Yoon-G became the host of the new show, K-pop Tasty Road with U-KISS's Eli Kim, combining the Korean wave and food into one show.
