F(x) Wiki

Chrystal Soo Jung (크리스탈수정) better known by her stage name Krystal, is a Korean-American singer, currently based in South Korea and a member of the Korean-pop girl group f(x). She is the younger sister of Girls' Generation former member Jessica Jung. Discovered by SM Entertainment in 2000, she began filming for commercials and music videos by 2002.


Early life[]

Krystal was born in San Francisco, California, where her family from South Korea settled in the 1980s. During a family trip to South Korea in early 2000, when Krystal was five years old, she and her sister Jessica Jung were spotted by a talent agency SM Entertainment, which earned her a cameo appearance in Shinhwa's "Wedding March" music video. The agency saw potential in both Krystal and her sister and offered them singing and dancing lessons, opting to professionally train them in a singing career. However, the offer was turned down by her parents, reasoning that Krystal was too young. Therefore, her parents at first only allowed her older sister to join the agency, who debuted as a member of girl group Girls' Generation in August 2007. She is fluent in both English and Korean.

In 2002, Krystal began appearing in television commercials. She first appeared in a Lotte commercial with Korean actress Han Ga-in. In 2006, her parents allowed her to join SM Entertainment, and the agency enrolled her in dance classes, including hip hop and jazz.


She attended Korea Kent Foreign School and Hanlim Multi Arts School after moving to Korea. Krystal was currently admitted to Sungkyunkwan University and will be attending in 2013 along with Kara's Ji Young. They majored in acting/theater.


A teaser trailer of f(x) was released via YouTube on August 24, 2009. The group's debut digital single "LA chA TA" was released on September 1, followed by a 40-second teaser of the corresponding music video revealed on YouTube. The group debuted on September 2 in a showcase specifically designed to introduce the group, in an event held at the Samseong-dong Fashion Center. On September 5, f(x) had their first broadcast performance on MBC's music show Music Core.
