Demi Lovato is also a Disney star, but she had some troubles.

We know at that time that she suffered from anorexia-bulimia, or more precisely anorexia binge-purge subtype. After, she said that she was bipolar.
But her eating disorder didn't make her look so different during the last years.

Here she is in 2010. She looks like a pretty normal 18 year old girl. Not too thin, and not fat either.

In 2011, she looks as good as she was the year before, with some tattoo on her rib cage.

And this year, after getting some help about her body's issues, we have a normal Demi Lovato, a bit heavier. I have to say that she seems to get fat in her legs and on her hips, but her curvy body is more a woman's body, than a teenager's.

It's nice to see some stars who doesn't look like they didn't go through puberty!
