Tony An (토니안) (born on June 7, 1978) is a South Korean singer best known for being part of the popular K-pop boy band H.O.T.. After H.O.T. disbanded in 2001, its ex-members Tony An, Jang Woo-hyuk and Lee Jae-won formed the dance music trio JTL. Eventually, JTL unofficially disbanded as each member, including Tony, released their solo material. He is also the CEO of TN Entertainment, a music entertainment company; Skoolooks, a school uniform company; and Shinenihs, an undergarment company. Popular comedians Jeong Hyeong-don and Jo Hye-ryun were both part of TN Entertainment. He studied stage performance at the graduate level at Dongguk University.
Solo career 
Recently, Tony made his hair shorter like in his late H.O.T - JTL days and changed his genre to fast paced soft rock songs and gave a speech, telling about his views on his former H.O.T. members, and how he tried to contact them. He also released a music video title "Melody" featuring SAT from his special album, "Untold Story".
On April 28, 2008 Tony came back with a new special album entitled "Look Blank", with its principle song "Wallet". In September 2010, Tony completed his 2-year army duty and released a new song, "Going To Meet You Now". He released an EP titled 'Top Star' in February of 2011 and after leaving as MC for the popular #1 Kpop chart show Mcountdown! in 2012 he released a single called "Beautiful girl" which also features Hyun Jun of SMASH.
Tn Entertainment 
After Tony wanted to pursue a solo career during his JTL days, he created his own label, Tn Entertainment. Artists under this label are Tony and former Click-B member Yoo Ho-suk, going under the name "Evan", along with Jung Ju-ri, Shin Bong-sun and others. South Korean comedian and entertainer Jeong Hyeong-don was the member of this company. TN Entertainment also debuted a boyband named SMASH, who released a PV for their debut song "비상[Emergency]" on August 14, 2008. Tony collaborated with SMASH in February 2012 with 'Get Your Swag On'. They promoted the song together on various live music shows.
When JTL was created, Tony was the lead vocal for the group and not just a back-up vocal and English rapper. H.O.T. fans had mixed feelings for JTL. Many of JTL's music videos were boycotted. However, things changed around when JTL held a 'Guerilla Concert' in front of 12,133 fans.
Personal Life 
It was announced in April 2013 that Tony is in a relationship with Girl's Day Hyeri. Both agencies have confirmed the dating of the two idols. The agencies of both are aware of the two’s meetings, according to Sports Seoul, who says that the agencies have said, “It’s true that they’re meeting with fond feelings… They’re still at a stage where they’re getting to know each other. Please look over them fondly.”Tony’s agency, TN Entertainment, confirmed over the phone, “Tony and Hyeri started to meet in March… They’re currently getting to know one another,” and “It’s true that they’re seeing each other. It’s been about 2 months now, so it’s hard to call it a ‘relationship’ at the moment. They are getting to know each other with fond feelings.”
