Pop superstar Mariah Carey's recent workouts have given her the body of a teenager.
The singer, 38, reveals she can now wear her high school wardrobe.
"My jean size went down to my 10th grade size."
Carey has also cut out fatty foods and items cooked in butter, which she insists hasn't been easy - because it meant giving up her beloved macaroni and cheese.
She says: "It broke my heart... That's the thing that I have difficulty letting go of because that's comfort food." - Wenn
