Christopher Thomas Woo (born November 25, 1991), also known as Woo Sung-hyun (Hangul: 우성현) and better known by his stage name Kevin Woo (Hangul: 케빈우) is a Korean-American singer and television host currently based in South Korea. He is a former member of South Korean boy band U-KISS. He is a co-host alongside Jimin Park and Jae of Day6 of the popular Korean music talk show After School Club, which is conducted in English so as to appeal to foreign fans of Korean music. He is a former member of boy bands XING and U-Kiss.
Kevin was born and raised in Danville, California, where he lived with his parents and elder sister. His father is a CF director while his mother is a fashion model; his paternal uncle is Emmanuel Woo, who is an actor and a classical singer in Germany.
After auditioning in Korea during a holiday trip, he was scouted[by whom?] and thus decided to be a singer. At the age of 15, Kevin moved to South Korea with his mother to pursue his dream.
XING (2006 to 2008)
Kevin made his debut in the four-member group XING alongside Marumir (now also known as Kim Kibum), Yume and Cheon Hyesung. The groups first single, "In Your Hands," was released on December 14, 2006. Their popularity quickly rose and they were dubbed as the teenage SG Wannabe. After the release of T-Express in April 2008, Kevin withdrew from the group.
In December 2009, Kevin and Alexander, a fellow U-KISS member, released the single "Finally". The song was composed by Brave Brothers.
On October 12, 2011, it was revealed that Kevin and Eli of U-KISS would collaborate with Avex artist JAMOSA for her single "Together". The single was released on December 7 and the trio held release events at Lazone Kawasaki Plaza (December 9), Osaka Senri Selcy (December 10) and Asunal Kanayama (December 11). The song "Together" was then selected as the theme song for BeeTV's "sweetTV".
In 2012, Kevin and Soohyun sang "Remember", a song originally by the group UN. It was used in the soundtrack of the drama series Syndrome. On March 1, 2017, it was announced on U-Kiss's official fan cafe by the label that Kevin's contract with them had come to an end and would not be renewed.
In 2013, Kevin and fellow U-KISS members Eli and AJ debuted as uBEAT, the first U-KISS sub-unit. The sub-unit released their debut mini-album I Should Have Treated You Better with a title track of the same name. The title track was composed by hit-maker Brave Brothers, who Kevin had previously collaborated with on "Finally". uBEAT had their debut stage at Mnet M!Countdown’s special global edition in Taiwan.
In July 2010, Kevin alongside his bandmates Soohyun, Kibum, Kiseop and Dongho were announced to be part of the drama I Am Legend, acting as a rock band. This marked their acting debut, where the members would get to show their musical talents by playing instruments rather than just singing; Kevin was to play the guitar. Fans were surprised when they did not appear in the drama. No official report has explained the issue.
On January 5, 2011, Kevin participated in the musical On Air Live as the lead actor. He acted in a total of 26 shows, his last stage coming on February 14, 2011.
In April 2013, Kevin alongside bandmates Soohyun, Eli and Kiseop participated in the drama KPOP The Ultimate Audition, having small cameo appearances in three episodes as a senior idol group to the main cast.
In April 2013, Kevin and Soohyun were selected to appear in the Korean adaptation of the musical Summer Snow alongside Super Junior's Sungmin, Supernova's Sungjae, SS501's Heo Young-saeng and FT Island's Seunghyun. Their appearances lasted from April 2013 to June 2013. This was Kevin's second musical.
Variety show hosting
Kevin has several MC credits to his name. In February 2009, he joined Arirang TV's radio show Pops in Seoul to host the "All About You" segment alongside co-host Kim Isak. U-KISS bandmate Alexander later joined the duo as a host. U-KISS bandmate Eli joined them as the new co-host in early 2010, replacing Kim Isak. In August 2010, Kevin and Alexander were selected as the new MC's for Arirang TV's music show The M-Wave.
On March 17, 2011, U-KISS' Kevin, Eli, and Alexander quit MCing for Arirang's Radio School due to the loss of U-KISS members Alexander and Kibum from the group. After the release of a U-KISS album in the same year, Arirang replaced Radio School with an alternate program.
In mid-2011, Kevin was selected to MC the Korean Music Wave in Singapore alongside Miss A's Min, as well as Korean Music Wave in Malaysia with fellow U-KISS member Dongho. In November 2011, Kevin and bandmate Eli were selected as MC's for Mnet's English-language version of M!Countdown, US MCountdown.
In a Japanese survey through popular fortune-telling site Cocoloni, Kevin was ranked as the number one luckiest Hallyu star for 2012. 100 fortune-tellers participated in the survey, predicting the stars' fortunes through zodiac, blood type and other methods. When Kevin received the news, he stated: "I'm honored to be ranked first. I want to make this really happen this year. U-KISS will go on a Japanese tour and we will also release our album. Please keep supporting us and help us rank first on the Oricon chart."
