Girl group Rainbow's Jo Hyunyoung showed off her barbie body.

On the 21st, Hyunyoung posted on her Twitter, "During album jacket filming for Tell Me Tell Me! I'm definitely not doing this because I'm bored," along with a picture.

In the picture, Jo Hyunyoung is wearing a mini dress that revealed her skinny body. Her skinny arms and legs with a small face made her resemble a barbie doll.

Internet users who saw this commented, "Was she always this sexy?", "A doll is talking" and "I feel like her waist is going to break."

Rainbow finished their activity with their song "Tell me Tell me" last month and is currently getting rest.
