Christina Aguilera

A pregnancy weight gain is inevitable, but if you are a celebrity, you can’t afford yourself the luxury of keeping those extra pounds for a long time. Christina’s weight was up and down during her career, but after her second pregnancy, she tipped the scale at 200 pounds. However, after a short time off from The Voice, she returned skinnier than ever. We are not sure how the star managed to slim down so fast, or if she sought any nutrition therapy. Either her nutritionist came up with a magical weight loss eating plan, or she chose an easy way out – a liposuction or a tummy tuck, or maybe both.
