Known as BTS's personal choreographer and a dance guru, J-Hope is about to show his dance talents on MBC's "Under Nineteen." The 24-year-old star will be a dance tutor for the show's one episode to teach and guide the young hopefuls.

MBC announced, via K-Pop Herald, J-Hope would be featured on "Under Nineteen" upcoming Saturday, January 5, episode. The BTS member would share some insights and tips to the show's young competitors as they take on a mission to cover the group's hit song, "Fake Love."

J-Hope will also give these youngsters some advice and encourage them to be the best that they can be. Before being BTS's rapper, he is originally a street dancer and called the group's private choreographer because of his incredible dance skills.

In a teaser imaged MBC released, J-Hope would be wearing an all-black outfit. He looked joyful and gave the contenders a big smile. But when it was time to teach them his dance moves, he turned into a serious dance coach.

MBC's "Under Nineteen" is an audition program for the aspiring teenagers who want to be K-Pop idols someday. They are set to compete in different categories, from vocals, rap, to performance, to prepare them to form a new K-Pop idol group.

Aside from J-Hope, "Under Nineteen" also features Crush, the hip-hop double act Dynamic Duo, and Super Junior's Eunhyuk. They will be guiding the show's participants to sing, rap, and perform.

Talking about J-Hope, fans celebrate the many faces of the BTS member. According to AllKpop, the group's supporters described him as someone who was "born to act cute off stage, but to slay on stage."

In a community forum, fans compared the difference between J-Hope's looks on and off stage by sharing his photos. They said he looks like a president when he wears formal suits off-stage, a sexy and traditional dancer on-stage, a cute squirrel, a sunbaenim on-camera, a casual boyfriend, and an innocent symbol of nature off-stage. Hence, they found he completely turns into a different person when he is performing on stage.

Meanwhile, Seungri's sister, Lee Han Na, revealed she is close with J-Hope in an episode of MBC's "I Live Alone." The Big Bang member talked to her sibling about her friendship with the BTS rapper.

"One of the members named Hoseok (J-hope) went to the same music academy as me in Gwangju," she said. Seungri was surprised to learn that J-Hope went to the academy he owned. Lee Han Na then commended BTS for being enjoyably crazy.
