Mariah Carey Covers 'Shape' May 2012

Mariah Carey flaunts her toned tummy on the cover of Shape‘s May issue, on newsstands April 23.

Here’s what the 42-year-old singer had to share with the mag:

On having her twins, Monroe and Moroccan: “Pregnancy was probably the best and the hardest thing I’ll ever go through. I know for a lot of women, it can be wonderful and relatively easy. But for me, it was like ‘Okay, honey, do you have to do everything the hard way?’”

On losing weight with Jenny Craig’s eating plan: “I used to be able to slim down just by exercising more, but that’s changed. Since having the babies, I realize that 90 percent of losing weight is my diet.”
