Demi Lovato has long been open about her battle with drugs and an eating disorder.
While her latest documentary touched upon living with bulimia, she just got real about the huge toll the disorder took on her body.
Lovato shared a side by side of her at her skinniest and now.
The photo was made by @heartbyheartdemi, a fan account.
She talked about living with bulimia in her documentary "Simply Complicated," saying that she relapsed after her breakup with Wilmer Valderrama.
"What started the relapse was missing Wilmer. And when I feel lonely my heart feels hungry and I end up binging," she said.
