PSY

Park Jae Sang, better known by his stage name PSY, is a South Korean singer-songwriter, record producer and rapper. PSY is known domestically for his humorous videos and stage performances, and internationally for his hit single "Gangnam Style".
In January 2001, Psy debuted his full-length album Psy from the Psycho World!, for which he was fined by South Korean government authorities due to his album’s "inappropriate content".
In 2003, Psy was to be enlisted in the South Korean military as part of mandatory military service. Psy was excused from military duty due to working at a software developing company. In 2007, state prosecutors accused Psy of "neglecting" his work, holding concerts and appearing on local television networks during his period of prior employment. On October 12, 2007, the Seoul Administrative Court decided that Psy must be redrafted. Two months later, Psy was re-drafted into the military, before being released from duties in July 2009.
On October 14, 2006, Psy married Yoo Hye Yeon, a cello major at Yonsei University and his girlfriend of three and a half years. According to the Korean Broadcasting System, the couple were introduced by a mutual acquaintance. They now have twin daughters.
