Someone's already got their summer bod ready!

Demi Lovato went makeup-free and flaunted her perfect physique in a sexy one piece bathing suit on Instagram yesterday, and the singer has never looked more comfortable in her own skin!

The chart topper spent years battling addiction issues and an eating disorder, but these days she's found a way to move past her demons and simply be happy and free.

"Sometimes when I’m having bad body image issue days, I remind myself that I’d rather live in freedom from my eating disorder than worry about what people think about my body. I am more than a number and a jean size," she recently wrote on Twitter.

So how did she achieve this new outlook?

"Feeling better than I’ve ever felt. 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!!” she shared with her fans on Instagram.

What an inspiration!
