Mariah Carey has lost 70lbs since having babies Moroccan and Monroe. The singer 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 didn’t think I would ever be the same person.

How’d she slim down? Beginning in July, Carey buckled down with a nutritionist and a workout plan from Jenny (formerly Jenny Craig), keeping to a 1,500-calorie-a-day menu and thrice-weekly workouts.

“I feel incredible,” the singer tells Us, three months after her body transformation began. She and Cannon, 31, famously struggled to conceive their twins (born via C-section at 35 weeks) after a heartbreaking miscarriage.
