Demi Lovato, who is known to be an advocate of healthy eating habits, continues to inspire fans as she shows off the fruits of her commitment on the cover art for her latest single "Really Don't Care."

The actual cover only shows a bit of skin, but Lovato couldn't help to tweet a shot of herself looking fierce and healthy. The image shows off her flat midsection while the pop star is dressed in black leggings, a cropped jacket, and a triangle bikini top. She projects a don't-mess-with-me vibe, with her hands on her hips and an intense stare for the camera.

"Sorry it's a little pixilated"”it was taken of the computer monitor at the photo shoot. I ♥ this pic!!" Lovato tweeted.

The singer practices moderation to keep her body fit and trim. For instance, after having a pizza party with President Barack Obama at film maker Robert Rodriguez's home to talk about human rights issues, she switched to raw vegan pasta.

"Eating RAW has never tasted SO GOOD!!! Cheesy alfredo pasta"¦ KELP noodles and raw vegan "cheese' made from CASHEWS!" said Lovato on her Twitter account as she shared a photo of the delicious-looking entrée.

Indeed, Lovato has come a long way since entering a treatment facility for physical and emotional issues back in October 2010. Upon completing the three-month treatment and returning home, the singer acknowledged that she had had bulimia, harmed herself, and was "self-medicating" with drugs and alcohol "like a lot of teens do to numb her pain."

A year after that, Lovato released her third album, 'Unbroken', featuring the hit single "Skyscraper' which was lauded for its messages of self-worth and confidence. She has also become a judge for the show 'X-Factor' and is now involved with several social and environmental causes. In May 2013, she was cited for her dedication as a mentor to teens and young adults with mental health challenges at a National Children's Mental Health Awareness Day hosted by the Substance Abuse and Mental Health Services Administration in Washington, D.C.
