Yoo Seung-jun

Steve Sueng Jun Yoo (born December 15, 1976), also known as his Korean name Yoo Seung-jun (유승준), is a South Korean-born American singer, dancer, rapper and actor who became one of South Korea's most popular K-pop stars after his debut in 1997.

Yoo was born on December 15, 1976, in Seoul, South Korea.

He and his family immigrated to the United States when he was thirteen and settled in Buena Park, California.

Yoo made demo tapes of his rapping and dance skills and sent these to Brothers Entertainment, where he was eventually scouted and left California to start his career as a singer.

Yoo made his South Korean debut as a singer in 1997.

His first album West Side was a hit with the debut single "Gawi" ("gawi" or "가위" is the Korean word for "scissors" - in this context it translates to "nightmare" as South Koreans use the word to describe the rigid sleep paralysis which sometimes accompanies bad dreams).

Along with another single "I Love You, Noona," he won "Best Newcomer of the Year" at many award ceremonies.

Yoo gained popularity with his signature dance move "Gawi," in which he and his backup dancers lined up diagonally to perform the same moves in unison.

"West Side" sold a million copies.

In the summer of 1998, he released his second album 1998 V2 for SALE with "Na Na Na" ("나나나") as its lead song, where it and the music video topped the charts.

In the video, it featured actress Choi Ji-woo, who played as the internship teacher while he played as the troublesome student.

Many consider this album as the most successful of his career, as it won him Best Artist of the Year in multiple award ceremonies.

The album again sold 1 million records.

In 1999, he went on to release his third album Now Or Never, which contained the hit single "Passion".

Later that year, Yoo released his fourth album, "Over and Over," which contained the hit single "Vision."

During this time, he began to expand his career into China and Taiwan, with the release of the single "Can't Wait", which was a collaboration with Taiwanese singer Yuki.

Now or Never topped the South Korean charts with first week sales of 879,000 albums sold.

Setting a record for the highest first week sales ever at the time.

The album eventually sold close to 1.5 million units.

He also released music videos for two of his Korean songs that year for "찾길 바래" ("Wish you could find") & "어제 오늘 그리고" ("Yesterday, Today & Tomorrow"), the latter showing off a more sophisticated image.

In 2001, he released the single "Wow" from his sixth album "Infinity."

Though considered a disappointment critically and commercially compared to his last three albums, "Infinity" still debuted at No. 1 on the charts with first-week sales of 359,961 units.

The album went to achieve sales of over 600,000.

Yoo had repeatedly stated on television that he would fulfill his mandatory military service.

Yoo's music career ended in 2002 when he was accused of evading South Korean mandatory military service by becoming a U.S. citizen.

He was subsequently banned from entering South Korea, becoming the only person in history to be banned from the country for acquiring another citizenship.

Since then, Yoo worked as an actor in China.

But in 2002, just before he was to be drafted, he became a naturalized U.S. citizen.

As a result, the South Korean government considered it an act of desertion, and deported him, permanently banning him from entering the country.

In 2003, his father-in-law, who resided in South Korea, died.

South Korea's Ministry of Justice allowed Yoo temporary entry into South Korea for two days.

In 2006, he was featured on rapper H-Eugene's song "독불장군" ("Single Person").

The song's music video does not show Yoo's face, but shows him dancing and his silhouette.

In 2007, he released his seventh album Yoo Seungjun Vol. 7 - Rebirth of YSJ for his fans who stood by him through the highs and lows of his career.

The album was produced under the collaboration of production teams from the United States, China, and South Korea.

He released singles such as "Missing U," "Breakin' Love," "One For Me" and "Fireworks."

He earned a role in an untitled Taiwanese drama loosely based on Bret Easton Ellis's novel Less than Zero.

In June 2008, Yoo signed a 15-year contract with Jackie Chan's entertainment management company to become an actor.

He has since attempted to establish a name for himself in mainland China while continuing his singing and acting career.

In acting, he is best known for his roles as Jin Wuzhu in 2013 historical TV series The Patriot Yue Fei and Prince Wen in 2010 film Little Big Soldier.
