"Feeling better than I've ever felt," Lovato wrote. "It's all about self love. Tell yourself you're beautiful daily. Be gentle with yourself. Eat carbs without guilt and remember that life is too short to worry about what others think!!"
When ET spoke with her earlier this month at the Smurfs: The Lost Village premiere in Culver City, California, the former Disney star talked about her self-confidence after growing up in show business.
"Sometimes you can feel like an outsider," Lovato candidly admitted. "I'm a homebody. I don't really like to go out and do stuff that, like, 'young Hollywood' typically likes to do, so sometimes I feel like I don't fit in."
"But I'm glad that I don't, I love being myself and I love who I am," she continued.
