The mom of two gave us major fitspo as she shared a snap of herself on Instagram Tuesday, smoldering for the camera with modelesque swagger in a black low-back swimsuit. "Get your suit on! Never-been-seen footage from my Spring '16 photoshoot is on the website! ... #sunsoutbunsout," she captioned the photo. While the fashion mogul revealed the back of the swimsuit on the 'gram, she showed off the front of it while flaunting her curves in the one-piece bathing suit in a shot that appeared on her site. Jessica Simpson Heats Up Date Night in a Plunging, Low-Cut Look In that snap, Simpson's soft blonde waves cascade around her face and chest as she strikes a pose in the plunging Strappy Days Plunge Keyhole Maillot suit ($78 [originally $98]; jessicasimpson.com), which comes complete with cut-outs and multi-colored bands across the chest. In another photo, the "Irresistible" singer switches things up, rocking the multicolored, fringed Feather Dancer Plunge Fringe Halter Maillot ($84 [originally $106]; jessicasimpson.com), which she paired with a fur vest. Courtesy Simpson glammed up the look with gold, square-rimmed shades, chandelier earrings and a metal belt, throwing her head to the side and a hand on her hip as she modeled the one-piece. Of course, this isn't the first time Simpson has flaunting her killer bod. Aside from her body-hugging date night stylings, the businesswoman went back to her Dukes of Hazzard roots in March, showing off her toned legs and tummy in Daisy Dukes and a bikini top during her vacay in Cabo San Lucas, Mexico. Simply sizzling.
