Mariah Carey has lost 70lbs since having babies Moroccan and Monroe. The 'Shake It Off hitmaker - who welcomed the twins with husband Nick Cannon six months ago - has managed to lose significant weight, but admits she was worried she would never be the same again following the pregnancy. Mariah - who embarked on the Jenny Craig diet plan to shed her excess pounds - said: In the beginning, when I first had the babies, I had so much edema, water and swelling. Most pregnant women have that just in their feet. One day I was doing my thank-yous and I noticed it started rising up the leg, so I had edema. I didnt think I would ever be the same person. The first week, I lost 40 lbs of just water. It was just water, initially. When I started with the programme, I lost at least 30 lbs of weight that needs to be lost. The 42-year-old star struggled throughout her pregnancy and even had trouble when she was confined to her bed. Speaking on 'The Rosie Show, she explained: I had a really tough pregnancy. I was supposed to be on bed rest, but it was so bad then even bed hurt. I learned a lot being pregnant, watching my body change. Mariah felt particularly vulnerable while carrying her children, and is delighted to have her old body back. CM
