Kim Yun-jee

Kim Yoon-ji (Korean: 김윤지; born Christine Kim) is a South Korean singer and actress. She performs under the stage name NS Yoon-G (NS윤지) and debuted in 2009 with the digital single "Head Hurts" under JTM Entertainment. The "NS" in her name initially stood for "New Spirit", but was later changed to "New Star". Kim used her Korean name as a part of her stage name, as she found "Christine" too difficult for Korean people to pronounce.

Kim began dating musician Chancellor in March 2015 while working on music together. They had met two years prior to the relationship. The couple became estranged due to their conflicting schedules and ended their relationship in August 2017.

In September 2021, Kim married Choi Woo-sung, her childhood friend, first boyfriend, and a businessman. He is the son of comedian Lee Sang-hae, her late father's best friend, and singer Kim Young-im. They reunited as adults after having parted amicably as teenagers because they assumed that their fathers might object to their relationship. In an episode of Same Bed, Different Dreams 2, Kim revealed that after returning from filming Lift, she plans to begin having children with her husband.
