Mariah Carey has lost 30 pounds since the April birth of her twins. The singer flaunted her trim bod in a new commercial for the Jenny weight loss system. In July, Carey went to a nutritionist, went on a workout plan and kept to a 1,500 calories a day.
She told the mag that after the pregnancy, "I felt trapped in my body because I couldn't move." But now, she says, "I'm proud of how hard I worked to get my body back... I had to do this for me."
