With her hand on her hip, the 33-year-old shot a sultry look at the camera while sporting the hot dress which featured a low-cut neckline and slashes of nude panels.

The mom-of-two took the snap just before an appearance on "Good Morning America" where she credited Weight Watchers for helping her bounce back to her pre-baby figure.

Thanks to her healthy diet and frequent workouts, the singer has been looking amazing lately! On Monday, the blond bombshell was spotted wearing chic leather pants and a fur shrug to combat the cold and girl looked crazy good when she posted a makeup-free selfie a few weeks ago.

Besides wanting to stay healthy, there was one big motivation for Simpson to stay on the fitness track: Her upcoming wedding! The retail fashion mogul is gearing up to get married to fiancé Eric Johnson this year and we can't wait to see what she will wear.
