Demi Lovato certainly knows how to get our attention!

The 22-year-old singer/actress posted the above snapshot on Instagram over the weekend, and not only does she show off her smokin' hot bikini bod, but we also got a peek at her new dog Buddy!

So what's the starlet been doing these days to stay in shape? She posted a photo of herself at the gym last week and wrote, "8 min abs = 8 minutes of HELL," and the other day she tweeted, "I want success more than I want sleep.. And that's why nothing stops me from killing the gym on Saturday mornings..."

But fear not -- Demi definitely seems intent on keeping her famous curves! In a recent interview with Allure, the former Disney darling said she's proud of her fuller figure and even gave Kim K a shout out! "Kim Kardashian, say whatever you want about her, but she has revolutionized what's accepted with curves these days," she said.

We think she looks hot -- and we bet boyfriend Wilmer Valderrama does too!
