Working her ass-ets! Demi Lovato has been very upfront about her quest to stay fit and be healthy, and her hard work is clearly paying off. The "Heart Attack" singer, 22, posted a sunny shot on Saturday, March 28, wearing a neon bikini and holding her new puppy, Buddy. 

In the Instagram photo, Lovato's toned backside is facing the camera, showing off her impressive curves. 

"Regardless of what society tells you these days… You don't have to have a thigh gap to be beautiful," she wrote on Instagram in February. "It is possible to love your body the way it is. #fitness #health #acceptance#selflove." 

The former Disney star also celebrated a big milestone last week, ringing in three years of sobriety and praising her longtime love Wilmer Valderrama

"I wish I could put into words how grateful I am for this man right here," she captioned an adorable kissing pic. "But my love has grown to a level that words could never possibly express how much this man completes me. He's loved me the way I never thought I deserved to be loved and with this day marking my 3rd year sober… After sharing my ups, putting up with my downs and supporting my recovery… he still never takes credit and I want the world to know how incredible his soul is. I really wouldn't be alive today without him. I love you Wilmer."
