Beach-ready Demi dazzles in sizzling selfies

Eat your heart out, Mariah Carey!

Demi Lovato is making the summer heat even more scorching—no, sweltering—especially for her 56.8 million followers on Instagram, where she posted a string of photos, a lot of them selfies, showing her in various stages of undress.

Demi’s been going to the gym religiously—and she’s proud to show off the temperature-raising results.

The steel-voiced, 24-year-old pop star supports a lot of advocacies, among them LGBT, adoption and animal rights, but the former Disney star also wants her followers to “love your body the way it is,” whether they’re curvaceous or scrawny.
