Hard work pays off!

Demi Lovato posted a photo of her bare stomach on Instagram Tuesday, explaining to her followers why she hardly ever posts pictures of her belly button.

“I rarely post pics with my belly button showing because I’m normally insecure about showing my full stomach but I’ve been working really hard and thanks to @d.leith and his yummy food with @lockhartandleith I’ve been seeing progress so I thought I’d post this cause I’m feeling myself right now!!” Lovato, 24, wrote.

The singer regularly posts photos and videos on her Instagram account of her workouts, including her boxing lessons.

Lovato, who has battled with body image issues, has also taken to posting inspirational and motivational images of herself promoting body confidence.

Despite coming far, the singer revealed in April that she still has down days.

“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,” she revealed on Twitter.

“I am more than a number and a jean size,” she continued. “F— yeah!”

She’s also not afraid to indulge when she wants. While traveling for work in New York last month, the star dined at Michelin Star restaurant L’Appart at Le District with a group of friends.
