London: Pop superstar Mariah Carey has managed to lose 70lbs since having her babies earlier this year.

The 'Shake It Off' hit maker, who welcomed the twins with husband Nick Cannon six months ago, admits she was worried she would never be the same again following the pregnancy, as reported.

"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 didn't 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," said Carey, who embarked on the Jenny Craig diet plan to shed her excess pounds.

The 42-year-old star struggled throughout her pregnancy and even had trouble when she was confined to her bed.

"I had a really tough pregnancy. I was supposed to be on bed rest, but it was so bad then even bed hurt. I learnt a lot being pregnant, watching my body change," she added.
