Hot Mama Mariah Drops 30 Lbs With Jenny Diet

Good for Mariah! The proud, sexy mama of twins is showing off her hot new figure, thanks in part to the Jenny Craig diet plan and a sound exercise program.

The superstar singer joins other celebrity moms of twins who have bounced back with amazingly flat bellies and toned bodies, like Angelina Jolie, Jennifer Lopez, and Celine Dion.

And now 41-year-old Mariah Carey has become the brand ambassador of Jenny Craig and will soon pop up in television commercials and print ads. Mariah will share her post-baby tips tomorrow morning on GMA.

Mariah had gained about 70 lbs during her pregnancy to adorable babies 'Roc & Roe'. "The first week, I lost 40 lbs... of just water," she said on the new Rosie Show yesterday, admitting she suffered from edema. "It was just water, initially. When I started with the program(Jenny diet), I lost at least 30 lbs. of weight that needed to be lost."

At the moment, the 5'9" singer says she is bewteen a size 4 and size 6, but that she doesn't jump on the scale:

"I never weighed myself," Mariah says. "People will think I'm a liar but it's true. This is another cliché phrase, I'm a big boned girl ... I'm tall and so I always weigh more."

So, is there something else Mariah might have done to gain back that flat belly body? And have other celebrity moms done the same?

We're not here to burst ayone's bubble, certainly not Mariah Carey's. She looks gorgeous. But following her c-section births, did she cheat a little. In other words.....a tummy tuck? That's the cosmetic procedure that many celeb and non-celeb moms have and NEVER admit to it.

So, let's take a closer look at the tummy tuck. We found some educational information at the RealSelf website.

And we have learned that there is a mini tuck and a full tuck. And the average cost of a ummy tuck is about $8,300.

A mini tuck zeroes in on skin removal below the belly with a shorter scar. But the belly button itself, may be lowered during the surgery, whereas, a full tuck tends to keep the belly button sitting in a more normal anatomical location.

Boston plastic surgeon Stephen Delia explains the benefits of a full tuck: "A full tummy tuck involves skin/fat removal and usually muscle tightening as well and will help the abdominal contour above the belly button as well.".

Now, we don't know which mama celebrity might have submitted to a tummy tuck here and there, but we thought we would point out the other popular, but not talked about procedure that makes post-baby weight disappear instantly.
