In the sultry shot, the mother-of-two dons a teeny white bikini top and blue shorts as she stars into the camera and playfully puts her thumbs into her waistline, flashing her groin tattoo. The barely-there ensemble shows off Spears' enviable physique, too. From her chiseled abs to her sculpted arms, Britney has us feeling like we need to put in some more work (b--ch!) in the gym.

The "Toxic" hitmaker simply captioned the stunning new picture with a bunch of lipstick and high heel emojis. It also appears to have been taken on self-timer in her purple Christmas lights-adorned home gym.
