Gain, a member of K-pop girl group Brown Eyed Girls, caused South Korean popular composer and pianist You Hee-Yeol's nose to bleed.

Appearing as guest at the Christmas TV edition of You Hee-Yeol's Sketchbook, Gain delivered her hit duet, The Gaze, with Yoon Jong-Shin.

Clad in a short bareback dress, she caught the audience by surprise with a pole dance performance before she started singing.

Although performing a duet, there was no interaction between Gain and Yoon, who were seated at a corner. Instead, the 25-year-old songstress walked over to seduce the host, who was playing the piano.

You Hee-Yeol's Sketchbook, debuted in 2009, is a music programme that sees the host chit-chatting with his guests, who also perform with a live band. It is airs on KBS 2TV after midnight every Friday.
