Mariah Carey is not the same person she once was, in fact, she’s better.

The new mommy revealed she dropped an incredible 70 lbs. after giving birth to twins Morrocan and Monroe Cannon a little over six months ago. The singer debuted a newly trim body in an appearance on Rosie O’Donnell’s OWN talk show.

The diva talks about her diet and exercise routine, but credits much of her weight loss to the Jenny diet, formerly known as Jenny Craig.”It was just water, initially. When I started with the program, I lost at least 30 lbs. of weight that needed to be lost.”

The singer says she initially lost 40 pounds of water weight she delivered her twins, who weighed six pounds each.

She also voiced her concern for her body during the pregnancy, “In the beginning, when I first had the babies, I had so much edema… water and swelling. Most pregnant woman have that just in their feet,” Carey says. “One day I was doing my thank-you notes and I noticed it started rising up the leg, so I had edema. I didn’t think I would ever be the same person.”
