Wonder Girls member Hyerim revealed a photo of her younger self.

She posted on her Twitter today, "When I was 13 years old", along with an old photo.

In the photo Hyerim is still flaunting her innocent beauty. However, she does appear to be a bit thinner and is wearing her hair long and down. The photo gained a lot of attention because of her unchanged natural beauty.

Internet users who saw the photo commented ‘You were pretty since you were young,’ ‘So mature as a 13 year old,’ ‘You look younger now.’

Wonder Girls have been going back and forth from the US and Korea promoting their new song 'The DJ is Mine'.
