4minute Hyuna made her fans nervous with her stretching picture.

On the 24th, Hyuna posted on her twitter, "Recording~~~~~" along with a picture of her resting on a sofa, stretching.

In the picture, Hyuna is in comfortable clothing in jeans and a shirt, unlike her usual colorful and fancy looks on stage.
Also, her sitting pose showed off a flexibility that someone who just entered her 20s is not common to have.

Meanwhile, Hyuna bought much love for her duet song 'Trouble Maker' with B2st Jang HyunSong, showing a sexy performance and an addictive melody.
