The first photo featured Lovato sporting a black off-the-shoulder dress and dramatic smokey eye while smizing to the camera, a pose we know Tyra Banks would be proud of (she coined the term, after all).
Lovato turned up the heat even more for her second selfie, letting her long, luscious curls down as she flaunted her curvaceous figure in a black corset top.
And what would a photo shoot be without some glitz and glam? The brunette beauty snapped picture No. 3 in the mirror to highlight the outfit's intricate sparkle and feather detailing.
Lovato, who credits healthy eating, kickboxing and a strict workout regime for her seemingly flawless figure, seems to be feeling more confident than ever lately. Back in April, the former Disney star couldn't help herself from sharing pics of her burnt orange one-piece that featured a drastically low neckline.
