Shots of girl group SISTAR's member Hyorin in the recording room was captured.

Today, Hyorin's agency Starship Entertainment posted on their Twitter a picture of Hyorin singing in the recording room in a pink sweater. She wore shorts underneath, revealing the disappearing-pants fashion, and her sexy body line caught much attention.

Hyorin featured for Mad Clown who will be coming back in April.
