Come on fellas! That's a photo of her when she was still in school, not as famous as she is now, not having a job or a lot of money like now, not taking care of his own face or not knowing make-up..

when I was in high school, most of my female friends didn't really care about appearance, but when we graduated and went get a work, all of them (the girls) are glowing up..

Moreover I'm really sure most Jpop lovers, especially Ado-san fans will not really care about how she looks because the most important thing is her work in music! Her talent! Her voice!
