Pop princess Demi Lovato has revealed she's happy in her own skin these days after years spent struggling with self-image issues.

Back in 2010 the former Disney starlet [uuid=420456c3-9bdb-4d87-a005-f53271a60b41]checked herself into rehab[/uuid] seeking treatment for "emotional and physical issues," with Demi admitting to Seventeen magazine in 2011 that [uuid=bdac1d5c-cbdc-4d91-b6e1-d75c21fd62cc]she had previously suffered from an eating disorder[/uuid].

Having overcome her demons, Demi looks happy and healthy on the November cover of Teen Vogue magazine, telling the publication:

"I don't have the body of a model or Barbie. My main thing about being in the spotlight with my fans is, I want to be real to them.

The 21-year-old continued: I have my problem areas, but I'm happy in my skin right now. I'm not going to sacrifice my mental health to have the perfect body."

The X Factor USA judge also encouraged her fans to speak up for themselves when they're having a tough time, adding: "You've gotta be honest with people around you. And honest with yourself.

"When you're having a rough day, be like, 'I don't want to talk about this, but I need to get it off my chest.' If you have a secret—secrets make you sick."

2013 has been a huge year so far for Lovato. As well as having her album, [uuid=7d42a28e-3291-455f-95e4-4c32b3299723]new tour[/uuid] and X Factor USA commitments to contend with, the starlet is also [uuid=9e324085-8afc-432a-adb8-6b3d37a1941f]releasing a book entitled Staying Strong[/uuid] and [uuid=7cc51a8c-95ae-4360-849b-3f60d49bbf02]guest starring on the current season of Glee[/uuid].
