Jessica Simpson – 114 lbs

Almost any adult in this day and age loves a good Jessica Simpson song. However, it has been over a decade since the “Irresistible” singer released any new songs although, it doesn’t necessarily mean she has been away from the spotlight.

The 40-year-old has built an acting career, runs a fashion line called The Jessica Simpson Collection, and even published a memoir in 2020. As many mothers do, Simpson, too, went through bouts of weight gain during her three pregnancies. Nevertheless, she managed to bounce back into shape in no time by signing up with Weight Watchers, walking 14,000 steps and following “The Body Reset” diet, losing at least 100 pounds.
