Britney Spears Showcases Her Flat Tummy, Toned Thighs After Photoshop Flap

Back at it with the flawless selfies! Britney Spears flaunted her flat stomach and toned thighs in her latest Instagram photo on Thursday, March 24.

Less than a week after fans accused Spears, 34, of Photoshopping a bikini pic, the "Toxic" singer showcased her toned physique — featuring her fierce abs — in a billowing white crop top, teamed with lavender shorts. A gold bracelet and peep-toe platform pumps completed the skimpy ensemble.

Four hours later, the Grammy-winning singer shared another playful message with fans: "Being an adult is the dumbest thing I have ever done."

The mom of Sean, 10, and Jayden, 9, has shared multiple body-baring snaps via social media throughout the week, including one in which she modeled a barely there ensemble while golfing. It was the follow-up to the bikini shot, which fans pointed out seemed to be missing a bit of concrete under her arched back, causing them to speculate that she may have edited the pic to appear slimmer.
