Earlier today, SISTAR unveiled their latest video teaser featuring main vocalist Hyorin through their official Youtube and Facebook page for their title track, "Alone".

Proving to be just as glamorous as ever, the teaser emphasized Hyorin's beautiful figure with a tight dress and sparkling accessories that made her shine. Despite being dressed up to the T, Hyorin looked as if she was holding down her loneliness and pain.

Check out more teaser images of her stunning transformation below as you wait for SISTAR's return with their Brave Brothers produced track.

Their mini-album drops on April 12th!
