Mariah Carey
Known for her barely there getups and bodacious curves, Carey’s envy-inducing frame swelled with nearly 100 extra pounds during her pregnancy last year. Carey recently revealed that during her pregnancy, she suffered severe edema — swelling caused by excess fluid trapped in the body’s tissues — and that she feared she wouldn’t be able to regain her pre-babies body. And though the new mom had her work cut out for her following the birth of her twins, Monroe and Moroccan Scott, she eventually dropped the weight thanks to exercise and strict diet courtesy of Jenny (formerly Jenny Craig). Carey is now down to a size 4-6 and is the latest celebrity spokesperson for Jenny.
